China Suppliers IEC 60227-5 RVV PVC Sheathed Cord 300/500 V - Factory Direct Wholesale
Construction
(1) Conductors
Number of conductors: 2, 3, 4 or 5.
The conductors comply with the requirements given in IEC 60228 for class 5 conductors.
(2) Insulation
The insulation is polyvinyl chloride compound of type PVC/D applied around each conductor.
(3) Assembly of cores and fillers, if any
Circular cord: the cores and the fillers are twisted together.
Flat cord: the cores are laid parallel.
For a circular cord having two cores, the space between the cores is filled either by separate fillers or by the sheath filling the interstices.
Any filler are not adhere to the cores.
(4) Sheath
The sheath is polyvinyl chloride compound of type PVC/ST5 applied around the cores.
The sheath fill the spaces between the cores, thus forming a filling, but it is not adhere to the cores. The assembly of cores is surrounded by a separator, which is not adhere to the cores.
The assembly of circular cords has a practically circular cross-section.
Technical Performance
- Maximum conductor temperature in normal use: 70°C
- The use of the cable type 60227 IEC 53 comply with IEC 62440, which provides guidance on the safe use of electric cables with a rated voltage not exceeding 450/750 V.
