{Connector suppling of electric power}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an insulated type connection line of an underground distribution line.

Generally, electricity used in each home, office, and large-scale Confucius is supplied through substations equipped for each region. These substations are installed for the purpose of modifying voltage and current and distributing electric power. The generated power is sent to the user through the transmission line or the distribution line.

The substation is usually installed on the ground. In such a substation, the high-voltage electric current must be transferred. Most of the high-voltage electric wires are exposed to the outside. The high-voltage electric wires exposed to the outside are short- It was easy to induce, and there was a problem such as hurting the surrounding scenery due to the erroneously installed high-tension electric wire, and the electric wire was installed in the underground.

In embedding such wires in the ground, it is very important to provide a method of interconnecting the wires and safely protecting them from inflow of infiltration water. In the prior art related thereto, Korean Patent No. 10-0898143 And a ground wire which is embedded in the ground and connected by bolt fastening in the inside of the manhole can be effectively protected from external interference.

In the conventional technique, a pair of ground wires are mutually connected through a bolt and a nut, and a sealing agent is injected into the connecting portion in a state where the connecting portion is disposed in the connecting portion, thereby fixing the mutual fixing of the inflow water. There is an advantage.

However, when the underground wire needs to be replaced, it is necessary to reinstall the underground wire in a state in which a part of the underground wire is cut off due to the sealant injected into the connection part. Therefore, the work is troublesome and troublesome, and electricity is energized until the injected sealant hardens There was a fundamental problem that could not be used.
