High-Temperature Single-Phase Constant Power Electric Heat Tracing Cable

The heating element of the constant power parallel electric heating tape is a tightly and uniformly coiled heating wire wrapped around the busbar insulation. The heating wire is connected to the busbar sequentially at fixed intervals (heating section length), forming a stable parallel circuit along the length of the busbar after voltage is applied.

In constant power parallel heating cables, continuous heating resistive wires form a series of interconnected parallel heating sections – heating sections, each of which is independently operable and can be cut to size as required (except for fire-retardant constant power parallel heating cables).

Constant power parallel heating cables cannot be used alone; they must be paired with a suitable explosion-proof temperature controller and accessories that match the environment.

In areas of Factory Zone 1 and Zone 2 with explosive gas T4, the explosion-proof temperature controller is set not to exceed 110°C. The temperature sensor is mounted on the outer sheath at a high temperature point to ensure the surface temperature of the electric tracing does not exceed 130°C.
