Project Description

Given that copper is expensive, it is more common nowadays to use aluminum cables with a higher cross section compared to copper cables, and a particular joint is needed to connect these two cables together. These joints are used to connect a three-core XPLE cable to three single-core XPLE cables, a three-core XPLE cable to a three-core XPLE cable and a single-core XPLE cable to a single-core XPLE cable that have different cross sections or have a different type of conductor.

These joints are mostly used in city substations or at the entrance of the posts to connect three-core cables or older single-core XPLE cables to three-core cables or newer single-core XPLE cables.

  • Insulating tubing

  • Yellow tape
  • Semi-conductor tape
  • Insulating tape
  • Copper mesh
  • Two-layer tubing (red / black)
  • Medium voltage ferrule
  • Earth ferrule
  • Installation manual
  • Taped jacketing tubing
  • Earth kit (if the earth is tape shield)
  • Cable breakout (for the code PHJMP-31)
  • Room temperature ranging from -40 to +105 °C
  • Cross-linked polymer insulation
  • Flame retardant
  • Easy installation
  • In accordance with DIN VDE 0278, CENELEC HD 629.1S1, IEC60502-4 Standard
  • With UV protection layer
  • With unlimited lifetime / energized as soon as it is installed on the cable

To order a cable with specific cross section and conductor type, you can act as follows at the time of selecting the code.

For instance:

Transition joint with a voltage of 24kv for a 120 mm2 three-core cable to three 150 mm2 single-core with a copper ferrule PHJMP – 3124 – 120150 CU

Z = first cable cross-section (if the joint is three-core to single-core for a three-core cable) (mm2)
X = second cable cross-section (if the joint is three-core to single-core for a single-core cable) (mm2)
Y= (CU/ AL /BI) Type of ferrule
