SUSPEND INSULATOR FOR POWER-TRANSMISSION LINE STEEL TOWER

摘要

PURPOSE: A suspension insulator for a transmission line pylon is provided to maintain the sag and expansion of a transmission line naturally by supporting the transmission line by a windup spring of a roller. CONSTITUTION: A combining unit(10) includes a hollow part, a connection hole, a rotary ball, and a coupling rod. A combining piece is formed in an upper side of an edge(20). A connection plate is formed in a lower side of an insulator. A transmission connection unit(30) includes a roller(36). The windup spring is positioned in the roller. One side of a connection wire is wound around the roller. The other side of the connection wire is connected to a transmission clamp. The connection wire supports the transmission line when the transmission line connected to the transmission line clamp is sagged or expanded. A jumper wire support(50) includes a support rod, a spring, and a support hole. The jumper wire is inserted into the support hole.
