Introduction to three phase constant power parallel tracing zone

Name: Three phase constant power and combined electric tracing belt

Model: RDP3

Power: 30-60W/m

Voltage: 380 V

Specifications: 6.3x9.5mm

Maintenance temperature: 0-150 ℃

Temperature resistance: 205 ℃

Application: Mainly used for freezing insulation of various pipes and instruments. The maintenance temperature can reach 150℃. It can be used for explosive gas situations in Section y.i and Section 2 of the factory.

Principle of constant power and combined electric belt operation

Constant power parallel electric zone (limited power electric tube) constant heat per unit length. The longer the electric belt is used, the larger the total output power is, the longer the length of single loop is used, which can be used for freezing of high output power and high exposure temperature to prevent heat preservation and process temperature maintenance of piping, instruments, tank equipment heat preservation, heat tracing, heating, which can be used for explosive gases in the first and second zones of the factory. Inside the constant power electric belt is a parallel heating element, which is actually composed of coil resistance and gold heating element wrapped around two wires. The distance between the electric shock of the wire forms the entire heating section. The juxtaposition allows for a fixed length of shear and end connection in the field.

Characteristics of three-phase constant power parallel tracing zone

The characteristics of the three-phase constant power parallel tracing zone are that the three-phase parallel constant power electric zone is designed and manufactured according to GB3836.1-83 and GB3836-83, that is, "General requirements for explosion-proof electrical equipment in explosive environment" and "e Requirements for Safety enhanced Electrical Equipment". The explosion-proof grade "E Doge T3" is non-flame-retardant. After passing the test required by the enclosed electric heater and matching with the enhanced safety electrical accessories, it is suitable for the test points of the explosive gas mixture group in Section y.i and Section 2 of the factory, which are not directly affected by external force.
