Three-phase constant power electric trace heating

The heating element of the constant power parallel electric heater is a tightly and uniformly wound heating wire 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 when 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 separable for trimming according to requirements (except for fire-resistant constant power parallel heating cables).

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

In areas of Factory Zone 1 and 2 with explosive gas T4 groups, the explosion-proof temperature controller's set temperature should not 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 heating does not exceed 130°C.
