Electric heating cable is the use of electric energy heat for equipment accompanied by heat preservation products.According to the use of different equipment and environment, electric heat cable is divided into self-regulating temperature heating cable and constant power wattage electric floor heating cable.One of the constant power wattage electric heat cable is divided into series constant power and parallel constant power, it is mainly used for temperature requirements are high, the environment is more complex large diameter, long distance pipeline and large tanks and other equipment.The following is for the constant power wattage electric pipe heat cable installation conditions and electrical connection to do a brief description.
Installation conditions: Check the cross-section of the power supply line which receives the score of each constant power electric heat tracing cable, and this cross-section should be slightly larger than the interface of the electric heat tape cable core. The cross-section of the total power line should be not less than the sum of the cross-section of the sub-power line. The electric heating trace cable should with the control electric matching use, the control electric generally has the overload, the short circuit, the ground leakage protection and the temperature protection.
Electrical connection.
1, the factory supply electric constant wattage heating cable tape head two (or three) wire core to connect the power supply, strips out the electric tracing heat cable wire core, should be careful, avoids the wire core (multi-stranded wire) breaks the strand, makes the wire core cross-section reduction, causes the overload.
2, wiring, electric heat wire cable at both ends of the electric heating tape cable shall not touch with the conductive core wire and shielding layer.
3, in the explosion-proof occasions, must be equipped with explosion-proof thermostat and explosion-proof accessories compatible with the environment.
If necessary, the user can let the electric heat trace cable manufacturer to come to the person to guide the installation, can avoid because the installation operation is not proper to the electric heating cable the heat system use to bring the influence, or asks the electric heating tracing cable to install the professional installation team to carry on the installation. If in the process of installation and use encountered problems can always find manufacturers to solve, so that the electric heating system in need of use can be timely for the equipment heating tape preservation.
