Series Type Thermocable LR
Series type heating cables are desirable when heated lengths exceed the circuit limitations of our off-the-shelf constant watt THERMOCABLE®. Often used in long pipe runs in mining where power is scare and often expensive. A series type cable has a constant power output throughout its length and may be used to trace pre-insulated pipes to 3659 m (12000 ft) or more in length from one power supply point. This is a lightweight product, easy to pull into heat trace channels and provides proven long term performance and reliability.
Series type heat trace cable cannot be cut to length in the field. Each application must be engineered and a cable of the appropriate resistance chosen for the application (voltage, circuit length and power output).
Although long electrical circuit lengths are possible, the series type cable must be supplied in shorter physical lengths to permit conduit pulling. If installed above ground, series junction boxes may be used to connect the cables together; if buried, the cable may be spliced under the thermal insulation at these points.
