Shrink sleeve generally refers to cold shrink cable accessories cold shrink cable accessories is the use of elastomeric material (commonly used silicon rubber and ethylene-propylene rubber) injection molding vulcanized in a factory, then by expanding, lined with plastic spiral support the components of the various cable accessories. When on-site installation, these sets of pre-expansion joints in the cable end or after treatment, out of a plastic spiral strip internal support (support), pressing on the cable insulation cable accessories constituted. Because it is at room temperature by elastic recoil, rather than heat-shrinkable cable accessories with fire heat-shrunk, so-called cold shrink cable accessories. Early cold shrink cable terminations head just additional insulation shrink silicone rubber parts, electric field treatment still use stress or stress cone type tape wrapped type. Now in general are cold shrinkage stress control tube, the voltage level from 10kv to 35kv. Cold shrink cable joints, 1kv grade cold shrink insulation tubes for enhanced insulation, 10kv level using joints with inner and outer semi-conductive shield cold shrink insulation. Three core cable terminal bifurcation branch cold shrink sleeve. Cold shrink sleeve and EPDM (EPDM) rubber introduced a, shrink tube generally refers to the use of cold shrink technology tubular cable accessories, with insulation, sealing, protection and other functions. Cold shrink technology, also known as the pre-expansion technology, because it is at room temperature by elastic recoil contraction, rather than as heat shrinkable material to be heated and shrunk, so-called cold shrink technology. Shrink tube materials commonly used in silicone rubber and ethylene-propylene rubber. Shrink tube with a small, easy to operate quickly, without special tools, less wide scope and product specifications and other advantages. Compared with the heat shrink type products, without using tools heating, thermal expansion and contraction in the case can also be tightly sealed and not due to thermal expansion and contraction gaps. Product Features Editor 1, easy to install, only manual operation, without heating or the use of special tools, joints without hot melt or enhance sealing tape; 2, suitable for connecting a wide range of different specifications of the cable seal and can be used indoors, outdoor, aerial, buried into the water or on other occasions, electricity, communications, and other cable; 3, resilient tough, radial retraction force, permanent deformation, even after prolonged use of the cable remains permanent radial pressure, Seal tightly, excellent moisture, waterproof, dustproof performance; 4, due to EPDM has excellent resilience and "elastic memory", with seals "breathe", so can play excellent sealing effect, the wind swing Under dynamic environment can still maintain a very good sealing effect; 5, resistance to salt spray corrosion, acid, ozone resistance, aging resistance, weathering resistance, UV aging excellent performance; 6, high mechanical strength, softness, excellent The puncture resistance, abrasion resistance, flex resistance, mechanical properties of fatigue.
