PLYJACK – Self-Fusing High-Voltage EPR Tape

Plyjack is a high-grade, ethylene propylene rubber (EPR) self-fusing tape used for insulation and jacketing of low-, medium-, and high-voltage splices.
It provides excellent electrical, mechanical, and moisture protection ideal for field installation and repair.

Key Features:

  • High dielectric strength (> 30 kV/mm)
  • Self-amalgamating — fuses into a single homogeneous mass
  • Resistant to ozone, UV, and moisture
  • Excellent thermal ageing stability
  • Compatible with PVC, XLPE, and EPR insulation types
  • Continuous operating temperature: –40 °C to +90 °C
  • Emergency overload temperature: up to +130 °C

Typical Applications:

  • Primary insulation up to 69 kV
  • Joints and terminations in MV cables
  • Re-jacketing of damaged insulation
  • Moisture sealing of electrical connections

Standard Sizes:

  • 19 mm × 9.1 m × 0.76 mm
  • 25 mm × 4.5 m × 0.76 mm
  • Other widths and lengths available

Plyseal is a conformable self-fusing mastic compound used as a moisture and environmental seal for medium-voltage joints.
It can be overwrapped with PVC or EPR tapes to create a complete insulation and sealing system.

Key Features:

  • Excellent moisture resistance and conformability
  • Adheres to all cable materials — metal, rubber, or plastic
  • Remains flexible over a wide temperature range
  • Perfect for sealing and shaping irregular cable contours

Plytech MV tape systems combine Plyjack EPR tapes with Plyseal mastics and PVC overwraps, forming a multi-layer system that provides both electrical insulation and environmental sealing in one package.

Benefits:

  • Pre-configured kits for common MV cable sizes
  • Quick and reliable field application
  • Consistent performance for repairs and terminations
  • Trusted worldwide for electrical insulation performance
  • RoHS and REACH compliant — safe and environmentally responsible
  • High elongation and mechanical strength ensure tight, secure wrapping
  • Excellent dielectric performance up to 69 kV
