2.3Construction2.3.1conductorNumber of conductors: 2.
Each conductor shall comprise a number of strands or groups of strands,twisted together,each strand being composed of one or more flattened wires of copper or copper alloy, helicallywound on a thread of cotton, polyamide or similar material.
The conductor resistance shall not exceed the value given in Table 1, column 5.
2.3.2 lnsulation
The insulation shall be polyvinyl chloride compound of type PVC/D applied around eachconductor.
The insulation thickness shall comply with the specified value given in Table 1, column 1.The insulation resistance shall be not less than the value given in Table 1, column 4.
2.3.3Assembly of cores
The conductors shall be laid parallel and covered with the insulation.
The insulation shall be provided with a groove on both sides,between the conductors，tofacilitate separation of the cores.
