Raychem Power-Limiting VPL Cable

Raychem Power limiting heat trace cables VPL is a family of power-limiting heating cables designed for pipe heat tracing in industrial applications. Raychem VPL can be used for freeze protection and process-temperature maintenance requiring high power output and/or high temperature exposure up to 455°F (235°C) and can withstand routine steam purges and temperature excursions to 500°F (260°C) with power off.

Raychem Power-limiting cables are parallel heaters formed by a coiled resistor alloy heating element wrapped around two parallel bus wires. The distance between conductor contact points forms the heating zone length. This parallel construction allows the cable to be cut to length and terminated on site. The power output of Raychem VPL heating cables decreases with increasing temperature. Raychem VPL heating cables can be overlapped. The relatively flat power temperature curve of Raychem VPL ensures a low start-up current and high output at elevated temperatures.

Raychem VPL cables available in four models: 5VPL, 10VPL, 15VPL & 20VPL. Raychem VPL is approved for use in non-hazardous and hazardous locations. Raychem VPL cables meet the requirements of the National Electrical Code. For additional information contact us.
