Electric accompanied by tropical not hot reasons and solutions

Electric accompanied by tropical has been widely used in pipeline, equipment and container heat, heat preservation, heating. The electric accompanied by the tropical shall be according to the national standard requirements for production, testing and qualified, before leaving the factory. If the project installation is completed, there is no heat and other phenomena, there may be the following reasons:

1, check whether there is electricity

2, air switch is tripped, the reason is that the configuration of the air switch capacity is too small, can't carry the electric heat tape of the current

3, the working voltage is low

4, the end is not dealt with, the electric accompanies the tropical tail end of the two wire must be separated, must be used in the tail end of the junction box plus 704 sealant sealing, to prevent the entry of water Produces the short circuit

5, the electric accompanies the tropical shield net to retreat inside the insulation layer 10cm, prevents the shield layer and the conductive PTC layer short, produces the short circuit, causes the electric accompanies the tropical power outage

6, uses the DC500V direct current shaking table, shakes the test shield layer and the conductive wire core insulation resistance, the general insulation resistance is greater than 200MΩ per 100 meters. if produces is smaller than the above value, please check electric accompanies the tropical is not damaged

7, electric accompanies the tropical Own quality problem
