Silicone-filled Straight and Transition Joints LoviSil® K
For paper-insulated and polymeric cables U0 / U (Um) = 6 / 10 (12) kV Application LoviSil® K cable accessories are suitable for use on paper-insulated (PILC or PICAS) and polymeric (XLPE or EPR) cable. This system comprises two ways of protection: The electrical insulation is inside a polyester inner joint, provided by the combination of a polymeric tube set (primary insulation) and a high-grade silicone-based compound. This compound remains fluid, thus minimising the risk of discharge or dried out paper. When polymeric cables are used, the insulation is completed by fitting high-permittivity stress cones. The mechanical insulation is provided by a strong polypropylene outer sleeve, filled with a two-part polyurethane resin serving as long-term water block. A copper wire mesh serves as electrical screen. Tests This cable accessory has been tested and approved according to HD 628 / EN IEC 61442 and HD 629 (CENELEC). The test was carried out with a water pressure of 20 metres head of water, so that the joint also meets NEN 3628 and NEN 3609 standards. Items Supplied LoviSil® K joints are ordered on the basis of a modular system. There are four modules: 1. Basic module This module contains all the ‚hardware‘ for the joint. The type of basic module is dependent on the cable sizes, see table below. 2. Resin module This module contains all filling compounds for the joint, including the LoviSil liquid. 3. Cable module This module contains additional items (foam rings, stress cones, etc.) needed to finish the cable preparation. The items in the cable module depend on the cable size and the type of cable: G = paper-insulated cable X = 3-core polymeric cable X1 = 3 x 1-core polymeric cable 4. Stop end module With the stop end module you can make a end joint of a standard joint by replacing one of the cables by a plug.
