Rubber insulated power conductors and cables

HEAVY DUTY MINING POWER CABLES FOR MINES WITH SURFACE EXPLOITATION

TYPE: EpN 78 ( EpHN 78 )
STANDARD: JUS N.C5.365
NOMIAL VOLTAGE: 3.6/6 ¸ 20/35 KV
DESCRIPTION OF CABLE:

Three power condutors are insulated with Ethylene-propylene elastomer,and under and over the Insulation are applied layers of semi-conducting elastomer,which are used to protect the Insulation to action of ozone.Three Grounding conductors, which are covered with semi-conducting rubber are located in the interstices of the power cores in contact with semi-conducting layers of insulation of the phase conductors.
The braid of textile thread in reinforced thermosetting heavy duty Neoprene jacket,which increase resistance of cable to mechanical stresses.
The heavy duty Neoprene jacket is tough,acid ,alcali and to weathering factors resistant.Its resistance to flame, high resistance to abrasion and to mineral oils.

APPLICATION:

This cables are designed for use as a mining cables on high voltage heavy-duty mining equipment such as loading and excavatinng shovels and draglines,dredges,drills,cranes,stackers and other surface mining portable and mobile electrical equipement.
