POWERHEAT PHT is a constant power parallel circuit heating cable built according to the latest international standards. It is suitable for operating temperatures up to 285°C and for applications in safe or explosion-proof zones (ATEX). The cable has a constant power in watts per metre regardless of its length and at any temperature. As a parallel circuit heating cable, installation is quick and easy because it can be cut, branched and terminated to length directly on site without any need for special equipment or knowledge of the exact length when planning the electrical layout. Constant power cables, providing the same power in watts per metre, always require a control thermostat both to regulate the process temperature and to prevent overheating and burning.
