Improving the thermal performance of a control cable can be a balancing act. Some of the changes to cable construction that widen the operating temperature range can also compromise the cable’s electrical or mechanical properties. However, silicone and cross-linked polyolefins do a good job of striking that balance because they offer a wider temperature range, as well as improved wear and chemical resistance. This topic was explored in a recent white paper from LAPP Group.

The advantages

Both silicone and cross-linked polyolefins can dramatically widen the continuous use temperature range of control cables. For example, a typical PVC control cable can function in a temperature range of -40 to 90 degrees C. Silicone-based cables, on the other hand, work comfortably in a range of -50 to 180 degrees C.

The conductor material is also an important factor, as a coated conductor is necessary to protect the bare copper effectively against corrosion in higher temperatures. Tinned copper conductors should be used within a cable with a jacket made of silicone or cross-linked polyolefin.

Improved wear and chemical resistance is also an advantage of cables made from silicone and cross-linked polyolefins. Compared to traditional PVC cables, when silicone and cross-linked polyolefin cables have improved thermal performance, they also exhibit equivalent flexibility and flame performance, as well as improved wear resistance (for cross-linked polyolefin) and chemical resistance.
