General

CIAC Cold Shrink Joint offers a reliable, fast and easy-to-install jointing system to assure and maintain high network reliability, and can help you reduce the time, labor and cost involved in a variety of electrical cable applications. A silicone rubber joint body with integrated geometrical stress cones provides excellent electrical stress control. CIAC Cold Shrink Joints are designed to cover a wide range of applications and to accommodate the variety of cable and conductor types in the networks. The CIAC product line covers joint needs from 0-600V to 42 kV applications, and can be used for direct burial, as well as in manholes, vaults, cable trays, and junction boxes. All CIAC cold shrink products require no special tools, flame or training to install.

Unique Silicon Rubber Material For Joint Body

Silicone Rubber Is A Kind Of Preferred Material For Cable Accessories Due To Its Excellent Mechanical And Electrical Properties. For More Than 30 Years Silicone Has Been Used Successfully As High-Quality Electrical Insulation For Voltages Up To 400kV.
Silicone Rubber Features High Quality Electrical Insulation, Superior Corona And Tracking Resistance, Combined With High Elasticity. It Facilitates Multi Range Application, Where One Product Version Can Be Used For Various Conductor Cross Sections. Optimal Flexibility Ensures Easy Assembly Of The Accessories

Stress Control System

Electrical Stress Control Is Fully Integrated In The Silicone Joint Body By Well Defined Conductive Areas. Conductive Cones With An Exactly Defined Geometrical Design Over The Screen Cut Area Provide Excellent Electrical Stress Control. The Electrical Stress Control Of The Connector Area Is Made With An Integrated Conductive Screen Performing As A Faraday Cage. The Coverage Of Voids And Edges At The Connection Area With Void Fillers Is Not Necessary, And The Radial Electrical Field Can Be Controlled Easily.

CIAC Cold Shrink Termination Family
  1. Indoor Termination Up To 12 KV
  2. Outdoor Termination Up To 12 KV
  3. Indoor Termination Up To 17.5 KV
  4. Outdoor Termination Up To 17.5 KV
Shield Continuity: Shield Copper Mesh

In order to keep the Shield continuity of cables, extra Shield Copper Meshes are applied around the joint to provide shielding and protection.

Armorcast

For strengthening cable and splices, armorcast forms a tough, durable covering that will harden in approximately half an hour. Armorcast Structural Material is a flexible fiberglass knit fabric strip that has been saturated with a black urethane resin syrup. The material is rolled and packed dry in a sealed foil envelope. Armorcast Structural Material is completely safe for use in manholes, vaults, and other hazardous environments, because no heat source is required. No flames, electric heaters, or chemicals are needed. The only thing your crews will ever have to add is water.
