Cold Shrink Cable Accessories
Cold Shrink Cable Accessories is a component of various cable accessories made of elastomeric materials (commonly used are silicone rubber and EPDM) that are injection vulcanized in the factory, then expanded and lined with plastic spiral supports. During on-site operation, just put these pre-expanded parts on the end or joint of the treated cable, and then pull out the plastic support strips for internal support. Because Cold Shrink Cable Accessories relies on elastic retraction at room temperature, instead of shrinking by heating like heat-shrinkable cable accessories, it is called Cold Shrink Cable Accessories.
The early Cold Shrink Cable Accessories only used silicone rubber cold shrink parts for additional insulation, but the electric field treatment still used stress cone type or stress belt wrapping type. Now cold shortening stress control tubes are generally used. Our Suzhou Feibo Cold Shrink Cable Accessories has two types, namely cold shrink cable middle and cold shrink cable terminal, according to the withstand voltage level, there are 1kv, 10kv and 35kv. Cold Shrink Cable Accessories generally uses cold shrink stress control tube, and the terminal head kit uses cold shrink insulation tube for enhanced insulation. The 10KV cold shrink terminal also has a joint cold shrink insulation with an inner and outer semi-conductive shielding layer. The fork of the three-core cable terminal uses a cold shortening branch sleeve.
Cold Shrink Cable Accessories has the characteristics of small size, convenient operation, no need for special tools, wide application range and few product specifications. Compared with heat shrink cable accessories, it does not need to be heated by fire, and when the equipment moves backward or bends, it will not present the danger of the internal layers of the accessories being separated like heat shrink cable accessories. Compared with prefabricated cable accessories, although they all rely on elastic compression force to ensure the internal interface characteristics, it does not correspond to the cable cross section one by one like prefabricated cable accessories, and there are many specifications.
Cold Shrink Cable Accessories It is necessary to point out that before being installed on the cable, the components of the prefabricated cable accessories are without tension, while the Cold Shrink Cable Accessories are under high tension, so the cold shrink components should not have obvious permanent deformation or elastic stress relaxation, so it is necessary to ensure that they are within the storage period, otherwise there will not be enough elastic compression force in the later stage, resulting in no good interface characteristics. The above is all the content of Cold Shrink Cable Accessories.
