Explosion-proof equipment plant
Explosion-proof flexible heating cable of constant power is intended for heating and maintaining the process temperature of automation objects, tanks, pipelines and any other objects that require additional protection against freezing and icing.
A parallel heating element is located inside the constant wattage heating cable. The heating element consists of a high resistance alloy heating coil wrapped around three parallel conductors. The distance between the points of contact of the conductors determines the length of the heating zone. The parallel design allows you to cut the cable into pieces of the required length and terminate the cable directly on site. As the temperature rises, the output power of the heating cable decreases. The cable's relatively flat temperature curve provides relatively low inrush current and high power output at elevated temperatures.
The explosion-proof three-phase constant watt heating cable provides constant power output along the entire length of the heating surface. The three-phase heating cable is used at low temperatures to maintain the set temperature. The cable can be used in hazardous areas.
For better transfer of heat energy, it is recommended to use PG-TERMOKLEY assembly sealant.
