Universal tape-resin type J3SI 24 U (paper-paper/paper-plastic)
Application:
- As a TRANSITION JOINT designed for connecting and repairing a three-core paper-insulated cable of the H(A)Kny, H(A)KnFtA, H(A)KnFty, H(A)KnFpy, H(A)KnFpA type with three single-core polyethylene-insulated cables of the YH(A)KX(S), XH(A)KXS, XUH(A)KXS, XRUH(A)KXS, NA2XS(F)2Y type with a rated voltage of 8.7/15 kV and 12/20 kV
- As a PASS-THROUGH JOINT designed for connecting and repairing three-core paper-insulated cable type H(A)Kny, H(A)KnFtA, H(A)KnFty, H(A)KnFpy, H(A)KnFpA with a rated voltage of 8.7/15 kV and 12/20 kV. Technical assessment of the product for compliance with the PN-E-06401-04:1990 standard
Construction:
- Connection of working cores using thick-walled, pressed or screw connectors with a partition
- Reconstruction of proper insulation using crinkled, insulating impregnated paper
- Reconstruction of the semiconducting screen using crinkled, semiconductive impregnated paper
- TRANSITION JOINT: connection of the return wire to the lead and steel armour by means of constant force springs, secured with mastic and EPR tape to prevent resin penetration into the connection
- PASS-THROUGH SLEEVE: connection of lead and steel armours using springs with constant pressure force and a 50 mm2 tinned copper braid, secured with mastic and EPR tape, protecting against resin penetration into the connection
- Seals made of mastics and EPR tapes block moisture during operation of the device
- Reconstruction of the external coating by means of epoxy resin injection using the injection sleeve included in the kit
Properties:
- Efficient and uncomplicated installation
- Making a sleeve without the need to use an injection gun and heat sources, e.g. a gas burner
- Two types of joints for a wide range of core cross-sections
- Laying directly in the ground or in cable ducts
- The sleeve is adapted to work vertically, horizontally, and on an arc
Composition:
- The set is a complete set for three wires. The plastic packaging contains all the necessary elements to make a sleeve connection along with assembly instructions and material specifications
- The set does not include connectors for connecting working wires. Connectors can be ordered additionally
