Technical Data


Feature
. Mineral insulated heating cables shall have a maximum maintain temperature 550°C and a maximum continuous exposure temperature of 650°. Higher temperature / power capabilities may also be available depending on the application.
. They are suitable for heating of pipes, vessels, tank container, flanges and valves, even they can be used in floors or concrete wall structures.
. Mineral insulated heating cables sheath with seamless stainless steel or alloy. And inner heating conductor with high purity ≥99.6% MgO insulation.
. A wide range of resistances ensures the termination of a multitude of heating cable length with various outputs (up to 200 watts per meter) and nominal voltages (300 V or 600 V).
