RVV Light PVC Sheathed Cord 60227 IEC 52 - 300V Power Distribution Cables from China Suppliers & Factory
Construction
(1) Conductors
Number of conductors: 2 and 3.
The conductors comply with the requirements given in IEC 60228 for class 5.
(2) Insulation
The insulation is polyvinyl chloride compound of type PVC/D applied around each conductor.
(3) Assembly of cores
Circular cord: the cores are twisted together.
Flat cord: the cores are laid parallel.
(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.
Technical Performance
Maximum conductor temperature in normal use: 70°C
The use of the cable type 60227 IEC 52 complies with IEC 62440, which provides guidance on the safe use of electric cables with a rated voltage not exceeding 450/750 V.
