Application: mainly used for anti-freezing and heat preservation of all kinds of pipes and instruments. The maintenance temperature can reach 150℃. It can be used for explosive gas in y.I and II areas of the plant.

Working principle of constant power parallel electric heating zone

Constant power and combined heating belt (limited power electric heating tube) unit length heat constant. The longer the electric belt used, the greater the total output power, the longer the single loop length, can be used for high output power and high exposure temperature of freezing insulation prevention and process temperature maintenance of pipe, instrument, tank equipment insulation, heat tracing, heating, can be used in the first and second zone of the factory explosive gas. The interior of a constant power electric belt is a parallel heating element, which is actually composed of coil resistance wound around two wires and a gold heating element. The distance between the electric shocks of the wires forms the entire heating section. Parallel structures allow for fixed length shear and tail connections in the field.

Three – phase constant power and connection tracing belt characteristics

The characteristic of three-phase constant power parallel connection tracing belt is that three-phase parallel constant power tracing belt is designed and manufactured according to GB3836.1-83 and GB3836-83, namely “General Requirements for explosion-proof Electrical Equipment in Explosive Environment” and “Requirements for Safety Enhancement Electrical Equipment E”. Explosion-proof grade “EдT3” with non-flame retardant, through the enclosed electric heater requirements of the test, with increased safety type of electrical accessories, suitable for the factory Y.I and ii zone explosive gas mixture group test sites not directly affected by external forces.
