What are the hidden dangers of wires without insulating tubes

What are the hidden dangers of wires without insulating tubes? Let’s find out below:

Insulating pipe is a collective term. There are glass fiber insulating sleeves, PVC sleeves, heat shrinkable sleeves, Teflon sleeves, ceramic sleeves and so on.

The yellow wax tube is a kind of glass fiber insulation sleeve, which is an electric insulation tube made of alkali-free glass filament tube coated with modified polyvinyl chloride resin and plasticized. It has excellent flexibility and elasticity as well as good dielectric and chemical resistance, and is suitable for wiring insulation and mechanical protection of motors, electrical appliances, meters, radios and other devices.

Temperature resistance: 130 degrees Celsius (Grade B)

Breakdown voltage: 1.5KV, 2.5KV, 4.0KV

Color: red, blue and green colored threaded tube. Natural color tube is also available.

There are hidden dangers: it is very unsafe that the wires are not covered with insulating tubes. After check-in, the wires may be damaged due to some reasons, such as the aging of the wires, causing the wires to be short-circuited; at the same time, once the wires are broken, the wires cannot be changed at all, only the wall is knocked. land.

Standard operation: Insulation pipes must be added to the outside of the wire laying. At the same time, the circuit connectors should not be exposed to the outside. They should be installed in the wiring box. No joints are allowed between the branch boxes.

During construction, the wires are directly buried in the wall, the wires are not covered with insulating tubes, and the wire connectors are directly exposed.
