Accessories for Nuclear Environments

Raychem has developed a series of heat-shrinkable components and kits to help seal and insulate electrical connections in nuclear power plants. Made of heavy-wall, flame retardant, cross-linked polyolefin and pre-coated with a nuclear grade adhesive, these products are designed to withstand radiation levels and temperatures attainable inside nuclear stations’ containment buildings.

Raychem nuclear power products are designed specifically to satisfy the requirements of protecting many of the 200.000 connections made in the construction of these plants. Raychem nuclear accessories have been subjected to very stringent LOCA/HELB tests to verify their performance capability in hypothetical nuclear accident scenarios.

 

 

Cable Repair Sleeves

Heat-shrinkable wraparound sleeves are a fast, versatile and permanent method of repair for damaged cable outer sheaths. Upon application of heat, the sleeve shrinks and adhesive melts and bonds to the cable sheath, creating a permanent seal against moisture entry into the cable. Wraparound sleeves are useful for repairs to cable outer sheath where it is not possible to use tubular sleeves.

 

Stripping Tool

Stripping tool for extruded and bonded cable screens and primary insulation for cable diameters from 35 to 90 mm.

 

High Voltage Installation Tool Box

The High Voltage Installation Tool Box includes all necessary tools for installing Raychem HV cable accessories up to 145kV.

With this comprehensive range of tools you will always find the right tool for the job. From simple standard tools to special high voltage tools, the installation tool box offers outstanding quality for a fast and reliable installation.

ZCSM – Heat-Shrinkable Heavy-Wall Tubing for Low Fire Hazard Areas

This new low fire hazard material has been developed using the latest polymer technology to provide low smoke, low toxicity and low acid gas generation while being highly flame retardant and having a low calorific value.

 

ZCSM tubing is halogen-free and flame-retardant. A range of established tests, such as flame propagation tests, limiting oxygen index and temperature index have been carried out to assess the flame retardation properties of this material

Corrosion damage depends on the amount of acid gases generated when a material is burned, and therefore on the level of halogens and other acidic components in the insulation material. Pyrolytic analyses show only trace quantities of these substances in the ZCSM tubing. The low toxicity index rating derived from measurements of these and further Combustion products provide additional evidence of the material’s suitability for meeting special requirements of this kind
