China Suppliers Factory of 60227 IEC 53 RVV PVC Sheathed Cord – Rated Voltage 300/500V
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
- 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 does not adhere to the cores.
(4) Sheath
- The sheath is polyvinyl chloride compound of type PVC/ST5 applied around the cores.
- The sheath fills the spaces between the cores, thus forming a filling, but it does not adhere to the cores. The assembly of cores is surrounded by a separator, which does not adhere to the cores.
- The assembly of circular cords has a practically circular cross-section.
