RVV wire is a kind of sheathed wire, also known as light PVC sheathed soft wire, RVV cable wire is mainly used in medium and light mobile appliances, instruments and instruments, household appliances, power lighting and other flexible places, can transmit control signals, power signals, also suitable for laying in bridges and hoses. In the production of life is the most widely market demand for general-purpose products.
RVV cable implementation of the national standard "GB ∕T 5023.5-2008 part 5 flexible cable (wire) rated voltage 450/750V and the following polychlorinated ethylene insulation cable".
rvv cable national standards include the following aspects:
1, appearance standards, the wire must have certification mark, manufacturer, wire diameter, etc., ground with yellow-green insulation layer national standard wire national standard wire.
2, mechanical strength.
3, the sheath insulation (generally greater than 100MΩ) and voltage strength (500V or less).
4, wire resistance (a certain wire diameter, conductivity, length under no greater than a certain resistance).
5, high temperature shock under 150 degrees, low temperature -30 degrees under the wire shall not appear cracking, etc.
