Custom Nuclear Cable

Nuclear-grade cable needs to be high-quality and able to withstand demanding environments. These cables are often exposed to radiation and are used in many nuclear power plant applications including switchboard wiring, distribution and panel boards, control panels, and other applications that use up to 600 volts.

There are often strict standards to ensure safety and efficiency, and many nuclear applications require the cable to be able to shut down automatically if a failure in the circuit is detected. This stops operations of the equipment without releasing any harmful radioactive material into the environment.

Our Custom Nuclear Cable Solution

One Allied Wire and Cable customer in the nuclear power industry was looking to upgrade a wire they had previously purchased. Since cable flexibility was essential to their application and the customer was especially concerned with tear resistance, they decided stock cable wasn’t what they needed. With the help of their assigned sales representative, the customer decided to design a custom cable that would meet all of their needs.

This custom cable featured six tinned copper conductors at its core. Each conductor was 28 AWG and had color-coded Perfluoroalkoxy (PFA) insulation. PFA insulation offers great mechanical strength at high temperatures and low-temperature toughness, both of which are important for nuclear applications. A 28 AWG tinned copper drain wire sat parallel under the shield, which was made of tinned copper and offered a minimum of 90% coverage. The jacket was made of silicone rubber. Silicone rubber is known for its high tear and radiation resistance, making it a great fit for this custom cable.

Thanks to Allied Wire and Cable’s custom cable design expertise, this customer knew their custom cable would be flexible and durable, ensuring its longevity.
