RG7H1R

Application

The single core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from

1.8/3KV to 18/30KV and frequency 50Hz. They are suitable for installation mostly in power supply stations,

indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for

industries, switchboards and power stations.

Standards

IEC 60502 / CEI 20-13

Flame Retardant acc.to:

DIN VDE 0482 part 265-2-1

EN 50265-2-1

EN 60332-1-2

Construction

Conductor:

Conductor: Plain annealed copper with IEC 60228 class 2.

Conductor Screen: The conductor screen consists of an extruded layer of non metallic, semi-conducting

compound firmly bonded to the insulation to exclude all air voids.

Insulation: Rubber, type G7 .

Insulaton Screen: The insulation screen consists of an extruded layer of non metallic, semi- conducting

compound extruded over the insulation. The extruded semi-conducting layer shall consist of bonded or cold

strippable semi-conducting compound capable of removal for jointing or terminating. As an option, a semi-

conducting tape may be applied over the extruded semi-conducting layer as a bedding for the metallic layer. The

minimum thickness is 0.3 mm and the maximum resistivity is 500 Ohm-m at 90°C. The screen is tightly fitted to

the insulation to exclude all air voids and can be easily hand stripped on site.
