According to the Safety Regulations, low-voltage insulated conductors are considered as bare conductors. The cable is wrapped in a double layer of insulation skin, and the outer skin can be safely contacted under live conditions. Insulated wires are often used for overhead lines and must be able to withstand a certain amount of tension. Therefore, in the aluminum core of insulated wires that we often use, there will be one or more strands in the middle...

A circuit breaker refers to a switching device that can close, carry, and break the current under normal circuit conditions, and can close, carry, and break the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high voltage circuit breakers and low voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague, and generally 3kV and below are divided...
