Outdoor Hv Polymer Fused Cutout Switch GB1208 2006 Standard Available

1. A fuse cutout or also called drop out fuse, is usually used in transmission overhead lines and used to protect the distribution transformer from current surges and overloads.The Fuse in the fuse cutout will melt when there is overcurrent in the transformer ,to disconnect the transformer from the lines.This can also be opened by the linemen standing on the ground using a long insulating stick called a “hot stick”

2. The fuse cutout consists of three main parts

The fuse cutout body, a porcelain or a polymer insulator body that isolates the conductive portion from the supports to which the insulator is fastened.

The fuse holder, also called the insulating fuse tube, it contains the replaceable fuse elements inside. when the contained fuse melts, it opens the circuit, and the fuse holder drops and hangs from a hinge on its lower end. This hanging fuse holder indicates that the fuse has melted and that the circuit is open. The circuit can also be opened manually by linemen using the hot stick.The fuse holder may be replaced by a solid blade, which would allow the fuse holder assembly to be used as a switch only.

The fuse link, also is the fuse elements. is the replaceable portion of the fuse cutout that will melt and break the circuit when there is overcurrent went through it.
