product introduction

En-CST is new silicone rubber cold shrink tube with special appearance. It’s specially designed to improve silicone cold shrink tube’s resistance to puncture and other external damage. It is also for weatherproofing protection on cable connections or joint, mostly applied on cell sites, such as connection between jumper cable and connector (7/16 DIN, N type or 4.3-10 connector) on RF equipment (RRU, Antenna and passive device), and joint between feeder and jumper cable. Comparing with tape sealing protection, time of installation is much shorter (15-30 seconds), more convenient, uniform waterproofing quality.

Silicone Cold Shrink Tube

Applications

1. It is widely used for waterproof seal in coaxial cables on telecommunication base stations, N-type connector, 1/2 jumper, Din head and 1/2 jumper connector;
2.It can be used as a waterproof seal for cable television connector;
3. It can be used as a waterproof seal for connecting wires and cables;
4.Insulation seal for other types of connection;

Inflatable Duct Sealing System for Power Cable (IDSS)

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℃.
