RVV Light PVC Sheathed Cord - 60227 IEC 52 - 300/300V - China Suppliers & Factory Solutions
Construction
Number of conductors: 2 and 3.
The conductors comply with the requirements given in IEC 60228 for class 5.
The insulation is polyvinyl chloride compound of type PVC/D applied around each conductor.
Circular cord: the cores are twisted together.
Flat cord: the cores are laid parallel.
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.

Frequently Asked Questions
What are the conductor specifications for 60227 IEC 52 cables?
The cables feature either 2 or 3 conductors. These conductors are designed to comply fully with the requirements specified in IEC 60228 for Class 5 conductors.
What materials are used for the insulation and sheath?
The insulation is made of a polyvinyl chloride compound of type PVC/D applied around each individual conductor. The outer protective sheath is made of a polyvinyl chloride compound of type PVC/ST5.
What is the difference in core assembly between circular and flat cords?
For circular cords, the core assembly consists of cores twisted together to form a practically circular cross-section. For flat cords, the cores are laid parallel to each other.
What is the maximum operating temperature and rated voltage limit?
Under normal use, the maximum conductor temperature is 70°C. The cable type 60227 IEC 52 complies with IEC 62440 guidelines for the safe use of electric cables with a rated voltage not exceeding 450/750 V.
How does the sheath structure protect the inner cores?
The PVC/ST5 sheath fills the spaces between the cores to form a solid filling, but it does not adhere to the cores. Additionally, the core assembly is surrounded by a separate separator layer that also does not adhere to the cores, allowing for easier stripping and termination.
What quality assurance processes do you implement?
We employ a multi-layered quality verification process that includes incoming material analysis, production phase monitoring, intermediate product validation, and final output certification, backed by complete batch traceability and digital documentation.
