Cold Shrink Joints - QS1000 & QS20003M QS1000 and QS2000 one-piece cold shrink joint bodies are manufactured from a specially formulated silicone material, which provides flexibility, easy installation at low temperatures and superior electrical performance over a wide range of operating temperatures. The finished body is expanded and loaded onto a removable supporting core, which allows the joint to be installed without the need for tools or heat. 3M QS1000 and QS2000 bodies are injection moulded and consist of three layers. A semi-conductive electrode, which forms a Faraday Cage around the connector, a high permittivity insulation layer, which both insulates and stress controls, and an outer semi conductive layer which ensures all screens are at earth potential. In the QS2000 body it also has two inner stress control elements to provide the proper electric field distribution for the higher voltage classes. All finished bodies are tested after manufacture and undergo AC Withstand and Partial Discharge testing. All joint types have been tested in accordance with VDE 0278, HD 629 and/or BS7888. Details of type tests are available upon request.
