Sigmian CTE is a high-output, ATEX-certified self-regulating industrial heating cable for heating outdoor areas, concrete, pipelines and vessels. It is primarily intended for applications where a standard-output self-regulating cable does not provide sufficient heating capacity.
The Sigmian product page specifies an output of 80 W/m. The technical datasheet gives the 90-CTE model a nominal output of 90 W/m at 0 °C when installed in concrete. The maximum continuous operating temperature when energised is +80 °C, while the maximum continuous exposure temperature when de-energised is +100 °C.
The heating cable operates at 230 V and is suitable for both non-hazardous and hazardous Ex areas.
Product code: 53137980
Applications
The CTE heating cable is suitable for:
- ice and snow prevention on industrial outdoor areas;
- heating open pump stations and technical areas;
- frost protection of ramps and loading areas;
- helipad heating;
- heating concrete surfaces;
- freeze protection of pipelines and vessels;
- process temperature maintenance;
- hazardous areas requiring ATEX-certified equipment.

Selecting and controlling the heating cable
The actual output of the CTE cable depends on the installation environment and cable temperature. The permitted heating circuit length must be selected according to the switch-on temperature and circuit breaker rating.
A self-regulating heating cable reduces its output as the temperature rises but never switches off completely. A suitable thermostat must therefore be used for accurate temperature control, lower energy consumption and a longer cable service life.
In Ex areas, connection kits, junction boxes, cable glands and control equipment must comply with the hazardous area classification of the installation site. The system must be designed and installed by a suitably qualified professional.
