The present invention relates to a fireproof insulating busbar manufacturing apparatus and a fireproof insulating busbar manufactured using the same, and more specifically, to the surface of the aluminum (AL) and copper (CU) busbar, By coating polyvinyl chloride resin (PVC), it is excellent for insulation of electricity emitted to the outside, thereby improving electrical conductivity, and improving production efficiency and safety compared to the conventional busbar coating manufacturing method, thereby reducing economic cost. Fireproof vinyl coating prevents damage to busbars due to high heat in case of fire, and can easily change mold dies according to busbars of various sizes. It is economical and improves production efficiency and shortens production period. The present invention relates to a manufacturing apparatus and a fireproof insulating busbar manufactured using the same.

In general, busbars have been used a lot of cables (Cable) in the past as a medium for transmitting electrical energy, but because of the many advantages of the busbars are used as a substitute for cables.

The similarity between the busbars and the cable in terms of structure is that they have conductors and insulators, but the great advantage of the busbars is that they can deliver more electrical energy to conductors of the same volume.

The cable uses vinyl or rubber to protect or insulate the conductor, but the busbar maintains the shape of protecting the conductor and the insulator by using a metal duct.

As such, the busbar is rapidly used as it is recognized in the advantages of a large-capacity system, and compared to the past, the current building system is becoming larger and larger, and is a building for a purpose that requires energy of various capacities. In line with this trend, busbars can be installed in harmony with modern buildings due to their safe and low energy loss.

In addition, the booth bar is supplied in various ways to buildings of various fields such as factories, buildings, apartments, large discount marts, officetels, research complexes, department stores, tunnel semiconductors, LCD factories, skyscrapers, ultrahigh voltage substations, new airports, and ports.

However, the conventional busbar uses copper busbars by winding an insulating protective film on the surface by hand and tapes them, thereby reducing production efficiency. The copper busbars use copper (CU) as a whole, thereby increasing costs. Therefore, the economic burden is large, the protective film for insulation is weak, the safety is low, and in case of fire, the insulator is weak, so that the busbar melts in high heat.

Accordingly, the present invention has been made to solve the above conventional problems,

Compared with the conventional busbar coating manufacturing method, the production efficiency and safety are improved, thereby reducing the economic cost, and the purpose of preventing the breakage of the busbar due to high heat in case of fire by the plastic coating material for fire resistance.

In addition, the present invention is easy to change the mold die to match the busbar of various sizes, economical, and has another object to improve production efficiency and reduce the production period.
