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.

64/110KV YJZGG Prefabricated Insulating Joint/ Straight Through Joint For 64/110kv Xlpe Cable

1. The body of joint is made of imported silicone rubber with good quality, so it is with high strength, elasticity and tear resistance as well as excellent thermal

aging resistance.

2. The body of joint has integral pre-fabricate structure with high voltage shielded, stress cone and insulating injection pressed integration, so it has excellent properties and easy to test as well as install.

3. The body of joint is analized and computed optimization by finite element software, so it has more resonable field-intensity distribution and high insulation safety margin.

4. The body of insulating joint and straight through joint is the same, the d ifference is just the handling of shielding on-site installation, insulating joint with one side insulated and the rest shielded while staight through joint full shielded.

5. The joint has completely sealed structure with high mechanical strength and good sealing performance.

6. Joint protecting is made of insulating copper case with high-intensitive T2 copper, and the moulded high-density PE material of its external surface is used for insulation and anti-corrosion with good mechanical protection and permanent waterproof sealing performance, which ensure the joint to run safely and reliably in the long-term under harsh environment.In addition, it can equip glass fiber reinforced plastic protective box as a strengthen waterproof measure accordingly.
