XLPE/CPE Instrumentation Cables

XLPE insulation is used because it provides strong electrical insulation along with good resistance to heat, moisture and many environmental stresses encountered in industrial installations. That combination can make it a useful insulation choice for instrumentation circuits that need consistent performance over long cable runs or in demanding operating conditions.

A CPE jacket provides a durable outer layer that can help protect the cable from conditions commonly encountered in industrial environments. It is often selected where abrasion, oils, weather exposure or other environmental stresses may be a concern. The jacket helps protect the insulated conductors and shielding contained inside the cable.

They may be used to connect field instruments, sensors, transmitters, monitoring equipment and control systems throughout a process facility. Typical installations can include manufacturing plants, chemical processing operations, energy facilities, utilities and other locations where signals must travel reliably between field devices and control equipment.

The decision depends largely on how much electrical interference the circuit may encounter and how much isolation is needed between individual signal pairs. An overall shield can provide protection for the cable as a whole, while individually shielded pairs can provide additional separation between circuits. Applications carrying sensitive signals or multiple independent instrument loops may benefit from the added isolation of individually shielded pairs.

Provide as much information as possible about the conductor size, number of pairs or triads, voltage requirement, shield configuration, installation environment and any applicable project specifications. It is also helpful to identify whether the cable will be installed in tray, conduit, exposed locations or another specific environment. These details make it easier to identify a construction that matches the application.
