RG16H1M20 12/20 KV 1 X 185 ROSSO

Description

Description

Standards

  • Product
    CEI 20-13; IEC 60502-2

Use and installation method

Suitable for energy transmission between transformer rooms and big power users. particularly suitable in places with a high fire risk such as airports, railway stations, ferry terminals, underground stations, road and rail tunnels; in rooms where equipment, switchboards and instruments are concentrated and where their protection is essential. For installation in open air, in conduits or ducts.
Can be laid underground, also if not protected, complying with art. 4.3.11 of CEI 11-17 standard.

Reference Construction Products Regulation 305/2011 EU and Standard EN 50575:
The cable is suitable for the supply of electricity in buildings and other civil engineering works.

Special features

Resistance to UV rays.
(ISO 4892-2:2013 / IEC 60811-501:2012 / 1000h)

Installation conditions

  • Minimum installation temperature: 0°C
  • Recommended minimum bending radius: 14 times the cable diameter
  • Recommended maximum tensile stress: 60 N/mm² of the cross-section of the copper

Construction

  • Single-core cables, insulated with HEPR rubber of G16 quality, under thermoplastic sheath.
  • Conductor: class 2, compact stranded wire, plain copper
  • Semiconductor layer: extruded
  • Insulation: HEPR rubber, G16 quality, lead free 
  • Semiconductor layer: extruded, cold stripping
  • Screen: plain copper tapes wrapped
  • Sheath: LS0H thermoplastic compound, M20 quality
  • Colour: red


N.B. The cable can be built in the three-pole version with helically wound cores. In this case, the initials becomes  RG16H1M20X followed by rated voltage.
