Applications: Used to provide insulation protection for cable outdoor termination in order to increase the creepage distance and avoid the formation of sewage for various of rod supporting insulators.
Pre-fabricated dry termination is integrally composited of stress cone and silicone rubber insulation material.
Dry GIS termination has composite structure of stress cone and epoxy sheath, making the surface of pre-fabricated stress cone clinged to the inner wall of epoxy sheath through spring assembly to reach reasonable interface pressure.
Cotran heat shrink terminations and joints are composed of a series of pre-expanded adhesive lined heat shrink tubes and necessary accessories. Heat shrink and provide excellent waterproof seal and electrical insulation. The terminations and joints are designed to be suitable for SWA/UA, XLPE/PVC/PILC, S/C, multi-core cable rated to 0.6/1kV.
Cotran heat shrink terminations (indoor/outdoor) are precisely designed to meet the parameters of international cable and cable accessories standards such as CENELEC HD 629.1 S1, IEEE-48, IEEE-404, IEC60502. Our heat shrink terminations offers reliable and consistent performance for longer service life. We have designed our heat shrink terminations for single core and 3 cores extruded UA, SWA/STA, CWS/CTW cable through 36KV.
Cotran cold shrink terminations and joints are composed of a series of pre-expanded silicone tubes and necessary accessories. The core is removed after the tube is positioned for installation over an inline connection, or terminal lug, allowing the tube to shrink and provide a excellent waterproof seal and electrical insulation. The terminations and joints are designed to be suitable for SWA/UA, XLPE/PVC, Single-core and multi-core cable rated to 0.6/1kV.

Cotran resin joint kits (CRJK), made from polyurethane resin (PUR), are designed for indoor/outdoor (weather exposed), underground applications. CRJK is a safe, simple, and reliable jointing solution for both straight type and branch type joints. Excellent electrical and physical properties of CRJK make them ideal for insulating and protecting electrical assemblies. The PUR resin also can be suitable for use as adhesives or sealants. Flame retardant PUR is also available.
The inflatable duct sealing system (IDSS) is a wraparound, inflatable mastic-lined bladder used to seal empty or filled cable ducts. When inflated to proper air pressure, the IDSS seals the duct, guaranteeing a reliable water block. The IDSS can be installed in cable ducts in manhole, vaults, buildings, cabinets, or anywhere a reliable duct seal is needed. Application include ducts containing multiple copper, coax, or fiber cable, customer premise cable entrance, and air pipes. IDSS can be installed between -40℃ to 75℃.
Cotran wraparound repair sleeve (CWRS) is designed to repair damaged cable jackets and protect cable or pipes where needs corrosion protection on undamaged ones. CWRS is made from modified cross-linked polyolefin (XLPE) with a hot-melt adhesive. When heating, the sleeve shrinks and the adhesive melts, thereby achieving tightly bonding between the sleeve and the cable. It provides an excellent solution of protection against mechanical stress, harshest environments, moisture and corrosion. CWRF is a fiber reinforced repair sleeve, which is composed of XLPE and fiber layer. It can provide better mechanical properties. CWRA is a fiber reinforced and aluminum layer reinforced repair sleeve, which is composed of XLPE, fiber layer, and aluminum layer. It can provide more stronger mechanical properties than CWRS and CWRF.
