High voltage cables should be fitted with insulated connectors at transformers and consumers end
and voltage stress cones or similar stress relieving device at feeder’s end.
All cable conductors shall be terminated by use of compression lugs or ferrules dependent upon the
type of termination. The compression ferrule should be the type where the conductor strands are
inserted through the whole ferrule and reach the bottom of the terminal.
Support for cleating of cables when entering panels should be provided.
In switchboards and distribution boards adequate space shall be provided for the use of a clip-on
amperemeter without causing undue stress on the cable conductors or connections.
The braid armour and the screen shall be separated from each other as well as from the conductors,
twisted and fitted as required. This shall be done without any reduction of the cross sectional area.
Where the screen shall be left disconnected (applicable for field instrument), it shall be sealed and
isolated with an isolating cap, which allows for insulation testing without any disconnecting.
Only one conductor is allowed in each terminal of a terminal block/row for external connections.
This is not related to terminals as integrated part of internal components (e.g. relays, contactors) of
the equipment. Two conductors may in certain cases be used in one approved type ferrule connected
to one terminal.
