Product description
The heat output per unit length of the parallel constant power electrical belt is constant. The longer the electric belt is used, the greater the total power output, and the longer the maximum length of single loop is. Mainly used for a variety of high temperature pipeline, equipment, storage tank, instrument insulation; High maintenance and heating temperature; Can be used in the factory zone one, zone two explosive gas occasions.
Features and advantages
1.The three-phase parallel constant power tracing belt is three parallel insulated copper stranded wires as the power bus bar, wrap the heating wire on the inner sheath insulation layer,and the heating wire at a certain distance (namely "length of heating joint")and the power bus bar AB-BC-CA-AB in turn...Repeated cycle connection.
2.In every two phases to form a continuous parallel resistance,when the bus bar through the three-phase electricity,the parallel resistance at the same time heating, thus forming a continuous three-phase power supply heating cable.
3.Three-phase parallel constant power tracing belt uses three-phase triangle power supply.
Details
Scope of application
The three-phase parallel constant power electric tracing belt is mainly used for anti-freezing, heat preservation and heating of various pipelines,storage tanks,pump bodies and instruments. The maximum maintenance temperature is 120ºC. Especially suitable for long distance , large diameter pipeline heating and insulation , can be used in the factory zone one , two zone of explosive gas mixture T3 group occasion .Technical data
