Electric Cable can be divided into building wires and flexible cables
Building wires can also be divided into three types according to the hardness of conductors.
H05V-U/H07V-U voltage class 300/500 or 450/750V. It is the most commonly used connection line for household wiring, mainly used for power supply, lighting, sockets, air conditioners and other daily household lines
H05V-R/H07V-R voltage grade is 450/750V, which can be used for home lighting lines. It is good to use when the wiring is soft and the circuit turns too much, which is convenient for electricians to wear pipes.
H05V-K/H07V-K voltage class 300/500V or 450/750V household decoration is generally not used, and it is suitable for flexible installation sites with strict requirements, such as electrical control cabinets, distribution boxes and various low-voltage electrical equipment.
What is a flexible copper cable?
Copper flexible cables are commonly used to connect portable equipment and appliances. Their flexibility allows them to withstand the movements or vibrations present in a particular application.Flexible copper cables are made from multiple strands of fine copper wire. The conductor is made of normal annealed copper of category 4 and 5. The cable has more than 6 different coloured cores. The insulation and sheath material must have the usual electrical and physical properties. Flexible copper wire is also soft, oil resistant, low temperature resistant and flame retardant.

Applications and features.
Power cables are suitable for use in wet and dry areas, conduits, pipes, slots, trays, antennas supported by messengers, and where excellent electrical performance is required. These cables are capable of continuous operation at conductor temperatures up to 90°C (normal operation in wet and dry locations), 130°C (emergency overload) and 105°C (short circuit conditions). 1/0 AWG and larger are rated for CT use.Household Electrical Wire,Household Application Copper Wire,House Wring Electric Wire,House Building Electric Wires
