Where extreme flexibility, long life and small conductors are necessary you will also need cables that can work in such environments. With modern nanotechnology comes the necessity to use robotics cable made from key conducting materials, high strength alloys and thin walled Teflon® wires. The smooth surfaces of robotic cables are designed specifically to prevent adhesion to adjoining cables.

However when your project requires new invention you may need to utilize the use of custom cables. Technology is changing more rapid than ever before, components are getting smaller while new space and air technology is expanding to reach further into space.

Another area where custom cables are required is in the development of defenses and in military use. In applications where the devices will be used by the military wires are required to withstand great pressures, low and high temperatures and other extremes. The military is not just for defenses but ever more for exploration. As the world has become more familiar we are now moving into uncharted extremes such as the polar ice caps, extreme ocean depths and outer space.

Also in the field of medicine, we have been growing into more detail and microscopic areas. With the implication of nanotechnology in medicine, medical cables are being required to perform in tight places, smaller technology and with enhanced outcome. With the enhancements of minimally invasive medical procedures techniques have been developed to use precise surgical instruments with the help of image guided tools such as miniature cameras.

Other areas where custom cables are required is in the development of cell phones, laptop computers, flat screen television, HD technology and underwater exploration. It is no wonder that with the advancement of all technologies comes the necessity for more advance, ever changing and adaptable cable and conductor technology.

Keeping To Military Specifications For Best Outcomes

Military specifications have come into some debate over the last 10 years or so. Both manufacturers and consumers of various products that require military cables that meet proper specifications discuss the advantages of adhering to these industry standards. All throughout, military specifications have remained the standard and the demand for mil-spec military wires as a wire product is as strong as ever.

Military specifications, or “MIL-Spec” for short, is used to achieve standardization objectives by the U.S. Department of Defense. For this reason, MIL-Spec custom cables and wires are built in accordance with these specifications.

Mil-spec wire and cable are suitable for demanding military electronic applications. Military wire may be used in high frequency electronic applications where high temperatures will probably be encountered. Military wire is specially designed for the harshest environments. Because it is designed for extreme conditions, MIL-Spec wire can be used for an array of purposes. Some applications include: shielding and protective covering, airframe wire, point-to-point wiring, antennas, bus-bar, ground wire, and bonding moving parts. MIL-Spec wire works well in applications requiring high-reliability where physical and environmental demands exist. However, depending on the military specification, individual MIL-Spec wires as well as specialized robotics cables will have certain applications for which they work best.

MIL-Spec wires come in numerous styles, sizes, and conductors. Some types of military wire include 10603 Hook Up Wire, Braid Tinned Copper Wire, MIL-C-13486 Wire, MIL-W-5086 Wire, MIL-C-3432 Wire, MIL-W-16878, MIL-W-16878D Shielded PTFE Cables, MIL-C-27500, MIL-C-17 Coaxial Cable, MIL-W-22759 Wire and many more. Types vary in specific configuration and uses to meet the requirements intended by the consumer. For example, MIL-Spec wiring coated with PTFE has excellent, stable electrical characteristics with low power loss. In the world of MIL-Spec wiring, MIL-Spec connectors also play a part. Like MIL-Spec wires, connectors are designed to military specifications and are intended for military and aerospace applications. They can be used for an array of purposes depending on the military specification.

A number of organizations and standards play a role in military wire and military specifications. Two major contributors are NEMA and the QPL. NEMA develops technical standards and shapes public policy, where the QPL identifies materials and suppliers who are approved for use on certain federal or government projects.

Medical and military cables serve vital functions in their respective fields. For asthma sufferers, bronchial thermoplasty is a novel, non-drug procedure developed to treat patients 18 years of age and older with severe asthma and is designed to provide improved asthma quality of life and control that lasts for at least 1 year. The Anesthesiology and Respiratory Therapy Devices Panel recently voted six to one in favor of approvable with conditions. The FDA issues the final approval of the device and while the FDA is not required to follow the advice of its advisory committee, it usually does.

Bronchial thermoplasty is a treatment performed through the working channel of a standard flexible custom cable bronchoscope that is introduced through a patient’s nose or mouth and into his or her lungs.

Controlled thermal energy is then delivered to the airway walls to reduce the presence of airway smooth muscle that narrows the airways in patients with asthma. The minimally invasive procedure, like many other flexible endoscopy procedures, is done under light anesthesia, and the patient typically returns home the same day of the procedure. Medical wires, like military wires, have been in use to perform similar functions as other types of cables, both in the operating room and out in the field.

Bronchial thermoplasty uses thermal energy to reduce the muscle associated with airway constriction in asthma patients. The Committee reviewed the results of the AIR2 Trial, which found that in the year following bronchial thermoplasty, treated patients with severe asthma experienced the following benefits: significant improvement in quality of life, thirty-two percent reduction in severe asthma attacks, eighty-four percent reduction in emergency room visits for respiratory symptoms, and sixty-six percent reduction in days lost from work. school or other activities. For more information about medical cables to treat various medical conditions including severe asthma, contact your local cable/wire experts to learn more.

Today’s small, ultra-flexible robots require coaxial cable designed specifically for each application. Here are guidelines to keep in mind when selecting wires and robotics cable for medical applications.

Modern medical robots are increasing in complexity while decreasing in size. Such changes are calling

for custom cable and military cable that are smaller and more flexible while containing a greater number of conductors. The design of a cable revolves around its conductors. Size is usually stated in AWG, which stands for American Wire Gage, but it can be given in millimeters squared. However, before considering size, the materials now required for small medical robots must be examined. Although copper has been the material of choice for many years, it lacks the tensile strength for small, flexible wires. High-strength copper alloys are now the minimum required. And as size decreases, the use of stainless steel and titanium is increasing.

The plating on a conductor is used to improve corrosion resistance and enhance solderability.

Traditional tin plating is giving way to silver because most high-strength alloys cannot be coated with tin.

However, stainless steel and titanium, which have very poor conductivity, can be gold plated to restore

enough conductivity for small wires.

The size of the conductor is determined by the current or resistance values that the circuit requires.

Often the conductor has the highest resistance that the designer can allow in order to keep

the cable small. Tables are available in most handbooks for copper; these must be

corrected—by using the %IACS factor—when using alloys. This factor is a percentage of

the conductivity of the alloy compared to copper. Because it is expressed as a percentage

of copper, it must be used as the divisor to correct the ohm/foot for copper to that of the

alloy.

Sometimes there comes a occasion when we have to select or buy something about which we hardly know anything. Purchasing a wire or cable for your home or work is a work like that and can become a daunting task for most of us. After all, our markets are full of products like these and most dealers’ stock wires of different sizes, length, thickness, and colour but how do we know which one is the best for us?

The best way to start your hunt of buying a perfect custom cable is to consult a friend, neighbour, colleague or family member who has some knowledge about the hardware. They may not be able to accompany you because of their routines but can definitely give you few practical tips that will help you in taking a correct decision.

Cable Shielding is one of the main points to consider during the purchase. Shielding is what ensures that the electric current flows through the cable smoothly without any danger. It also minimizes the issue of signal exit or entrance that can be caused by interference. There are mainly four types of shielding – foil, braid, spiral and combination of braid and foil.

A green cable with foil shield ensures that it is covered till the end and is generally cheaper that the other types of cables. Braids shields are majorly used in computers to terminate inter connections for controlling different applications. Its advantages include flexibility and longer structural integrity.

Cables with spiral shield are normally used for microphone, and audio cables. These also offer greater flexibility and longer shelve life. Combination shields come with total foil coverage and are strong but the disadvantage includes higher costs.

You can also go for Robotics cable, which can work without any problem within a temperature range of -40 to +80°C and ensure continuous twisting motion for flexing applications. Coaxial cable is another option if looking for electrical cable with an inner conductor and surrounded by an insulating layer.

Effective shielding prevents interference from entering or emanating from a cable

In the late 1800s, as the use of electricity was first being used for communications, interface reared its ugly head. The imperative for some form of mitigation became apparent. The first attempts involved using custom cable for wire spacing. Bare wires entered buildings and were forced closer to each other, twisting the pair was the preferred technique for reducing interference says military wire specialist. Look at early pictures of New York City; the sky is dark with thousands of wires for telegraph and telephone wires. Then radio came along, and radio broadcasts could be heard coming from the telephone wires. The need for shields became a problem begging for a solution. Wrapping the cables similar to military cable with grounding wires (a simple served shied), worked or fixed installations; but when the cable was subjected to flexing, the wrapped wires separated and interference returned. Enter the braider. Braiders were invented in the mid – 1800’s to manufacture shoe laces and other textile items. Tinsel wire, a flattened wire wrapped around a cotton or flax yarn, was used for the epaulettes on military uniforms. Early telephone engineers discovered that this was great, very flexible conductor for telephone earpiece cords. The tinsel wire could also be braided over the conductors in the earpiece cords to reduce radio interference. When the custom extrusion cable was not subjected to high flexing conditions of a telephone cord, tinsel wire could be replaced by simple strands of wire.

These days, the purpose of a shield is to prevent interference from entering or emanating from a cable. The three types of interference radio are: radio frequency interference (RFI), electromagnetic interference (EMI) and electromagnetic pulse (EMP). RFI was the earliest type of interference that engineers had to deal with, Early radio signals easily found their way into devices. Coaxial cables and shielded twisted pairs using copper eliminated most of this type of interference. Today, EMI has become more problematic because of high power transmission lines; higher magnetic fields, such as MRI machines in hospitals; and other high power applications. Copper may not offer much resistance to higher magnetic fields; therefore,the use of magnetic materials such as high permeable irons may be required. EMP is produced by the detonation of nuclear devices. When the hydrogen bombs were tested in the 1950s at Bimini Atoll in the South Pacific, circuit breakers at power stations in Hawaii were tripped by the EMP

wave from the detonation. Critical military and civilian circuits must be protected from

an EMP condition. These shields require the use of both high and low permeable materials

to reduce the effect of an EMP.
