Description

Description

Standards

  • International
    Nexans specification
  • National
    DIN VDE 0250 part 813

 

Application

WINDLINK® MV-RS (N)TSCGEHXOE was developed for special application condition in wind turbines.
The construction is torsion resistant by free hanging max. 100 m.
These cables are specified for medium mechanical stress and for operation under permanent influence of seawater and usage outdoor.

 

Design

Power-core
Conductor:
Copper, plain, flexible concentrically stranded circular, class 5 acc. to IEC 60228

Insulation:

  • Inner semi-conductive stress control layer, fixed with insulation
  • Elastomeric extruded special rubber compound RHEYCLEAN HV-EPR, quality better than 3GI3 acc. to DIN VDE 0207 part 20, based on EPDM, optimized wall thickness
  • Outer semi-conductive insulation shield layer, easy strip (thermostrip), compound basis EVA.

All three layers are extruded in one extrusion process and free of hollow space.

Protective-core
Conductor:
Copper plain, flexible concentrically stranded circular, class 5 acc. to IEC 60228
Conductor screen:
Extruded semi-conductive rubber

Inner Sheath
Extruded special rubber compound:
Quality better than GM1b, acc. to DIN VDE 0207 part 21, fulfils the requirements of EM1, nature colour, the filling of the interstices is integral part of the inner sheath and out of the same material, produced in the  same process with outer sheath.

Outer Sheath
Extruded special rubber compound:
Quality better than EM8 acc. DIN EN 50363-6, based on EVA,
water and oil resistant, flame retardant, abrasion and notch resistant,
colour: black, embossed marking e.g.:
WINDLINK MV-RS (N)TSCGEHXOE 3x25/25  18/30 kV INEXANSI year

 

Resistance to:

  • permanent movement
  • permanent vibrations
  • compressive stress
  • temporary influence of seawater
  • suitable for torsion of max. +/- 100°/m
