Heat shrinkable cable terminal head

Cold Shrink Cable Terminal is the use of an elastomeric material (commonly used silicone rubber and ethylene-propylene rubber) at the factory vulcanization injection molding, and then expanding, lined with plastic screw support components constituting the various cable accessories. On-site installation, these sets of pre-expansion joints in the cable end or post-processed to extract the internal support of plastic spiral rod (support), pressing the cable attachment on the cable insulation and composition. Because it is at room temperature by elastic recoil, rather than heat-shrinkable cable accessories with fire heat shrinkage, so-called cold shrink cable accessories. Early cold shrink cable terminal head is attached with silicone rubber insulation shrink components, electric field treatment still use stress or stress cone type tape wrapping style. Now in general are cold shrink stress control tubes, voltage level from 10kv to 35kv. Cold Shrink Cable Terminal, 1kv grade cold shrink insulation tubes for enhanced insulation, 10kv level uses with inner and outer semi-conductive shield connector piece cold shrink insulation. Three core cable terminal bifurcation branches cold shrink sleeve. Shrinkable cable terminal head with a small, easy to operate, fast, without special tools, wide scope and the advantages of low product specifications. Compared with heat-shrinkable cable accessories, without the use of heat, and after the installation will not move or bend dangerous disengagement between the inner layers as accessory like heat-shrinkable cable accessories (since shrink cable terminal head by elastic pressure clamping force). Compared with prefabricated cable accessories, though they are resiliently pressing force to ensure that the internal interface features, but it is not as prefabricated cable accessories and cable cross sections correspond, specifications. It must be noted that, prior to installation on the cable, components prefabricated cable accessories is no tension, and shrink cable terminal head is in a state of high tension, it must ensure that the storage period, cold shrinkable type component should not be significant permanent deformation or elastic stress relaxation, or can not guarantee that the cable is mounted on flexible enough clamping force, which can not guarantee a good interface characteristics.
