Type W Flat 2/C PORTABLE POWER CABLE 2KV

Application:

• This specification describes two-conductor flat Type W portable power cable with EPR (ethylene-propylene rubber) insulation for use in circuits not exceeding 2000 volts at a maximum conductor temperature of 90°C. Cables are intended for use on dc shuttle cars and other mobile mining equipment.

Also Known As:

Type W Flat Portable Power Cable, Type W Flat Cable, Type W Flat Power Cable, Power Cable, Portable Power Cable, Type W Flat Cable

Standards:

• The following standard shall form a part of this specification: ICEA Pub. No. S-75-381 for Portable and Power Feeder Cables for Use in Mines and Similar Applications (NEMA WC58).

Construction:

Conductors: 

Minimum Class H stranded annealed coated copper per Part 2 of ICEA.

Insulation:

A homogeneous wall of EPR insulation shall be extruded over the conductor. The average thickness of the insulation shall be specified in Table 3-7 of ICEA. The minimum thickness shall be not less than 90 percent of the specified average values. Physical and electrical properties of the insulation shall be in accordance with Par. 3.15 of ICEA.

Circuit Identification:

Colored insulation with one conductor black and one conductor white meeting the requirements of Par. 3.18 of ICEA.

Reinforcing Braid:

Each conductor shall have an open braid to facilitate adhesion between the insulated conductor and jacket.

Jacket: 
Two insulated conductors are laid parallel and a thermosetting jacket shall be extruded over the assembly in accordance with Par. 3.21 of ICEA.

Cable Identification:

All cable shall have an embossed print legend showing manufacturer, cable type, size, voltage, and Mine Safety and Health Administration (MSHA) Approval Number.
