1. General Information
Bartec PSBL heating tape is for electric trace heating for frost protection of pipelines and vessels in explosive atmosphere, two parallel positioned copper wires with a cross-section of 1 mm² an irradiated electrically conducting polymer is extruded, can be used in explosive atmospheres without temperature limiter and cut to any length due to the parallel current supply. Resistant to corrosion and chemical influences because of the external protective jacket. PSBL use Tinned copper braiding for electrical and mechanical protection which is easy installation due to high level of flexibility. Electrically conducting matrix responds to changes of the ambient temperature with an increase or decrease of the heating output. A flame-retardant, UV-resistant jacket protects the braiding against humidity and offers additional protection against mechanical stress. The heating system must be designed to ensure that the maximum operating temperature of 65 °C will not be exceeded when it is energized. When it is switched off, the heating tape can be exposed to a temperature of 85 °C, not more than 1,000 hours cumulated.
