product introduction

enRR-CST is new silicone rubber cold shrink tube (built-in Rubber Ring) with special appearance. It’s specially designed to improve silicone cold shrink tube’s resistance to puncture and other external damage. It’s a kind of good accessory 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.

Durable 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;

COTRAN Z551 Self-Fusing Silicon Rubber Tape

COTRAN Z551 self-fusing silicon rubber tape is composed of self-fusing silicone rubber and easily removed liner. It has excellent resistance to tracking, ozone, UV, corrosion, water and continuous operating temperature of -50℃～180℃. It can be used in dirty areas. Suitable for busbar insulation protection and phase identification, Insulation for terminations and joints of high-voltage power cables up to 35kV, Insulation for submarine cables, submersible motors, large-sized generators, automobiles, aero engines and other electrical equipment.

Wraparound Repair Sleeve

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.
