In order to guarantee the normal operation of the crosslinking cable accessories, must be the attachment of cable in the construction process to take necessary measures to eliminate the influence of insulation retraction.
1. heat straightening. The heating straightening process is also a process of eliminating the internal stress on the cable. Through the cable manufacturing process of heating and cooling part of thermal stress relieving reduce cable insulation shrank back.
2. joint fixed device. Crosslinking cable prefabricated type connector cable insulation installation strict size millimeters retraction tend to cause the breakdown of cable joint. So the shielding cover on both ends of the cable insulation groove stuck cable insulation prevents retraction of cable insulation.
