gui chao cable news: wire and cable conductor preheating matters needing attention-非凡电子娱乐

wire and cable is our life can be seen everywhere, wire and cable in the production process, we often encounter the conductor needs preheating,

however, the reasons for the preheating of the conductor and the establishment of process parameters is not enough, then the following small series to introduce the electric wire and cable conductor preheating precautions

1, in the premise of ensuring the stability of the line, so that the preheater and the nose as close as possible to avoid the loss of heat;

2, for the ul wire, the tensile strength of the insulation requirements, the first inspection arrangements for physical and mechanical properties test;

3, when the conductor surface moisture is more serious, should be cleaned before entering the preheater, to avoid the oxidation of conductors and spots;

4, in the production of debugging, disconnection and other abnormal treatment, should be concerned about the change of preheating temperature; if necessary, the need to temporarily shut down the preheater;

5, preheating temperature is too high, will cause the filling fiber shrinkage and carbonation, resulting in tensile strength decreased, please pay attention to check;

6, induction preheating only for bare conductor, the insulation core line invalid;

7, when the cable was escorted from the need to have some adhesion requirements, insulation adhesion should be slightly larger than the outside adhesion, the preheating temperature is set with the assessment criteria for adhesion;

8, for the purpose of eliminating the moisture for preheating, please try to use dry filled fiber material
