product details
The fuses are fitted in HV side of distribution transformer or distribution branches, used as short circuit and over-load protection as well as the opening and closing load current.
Description:
In electrical distribution, a fuse cutout or cut-out fuse is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An over-current caused by a fault in the transformer or customer circuit will cause the fuse to melt, disconnecting the transformer from the line. The cut-out fuse features with excellent over-current protection, high power frequency withstand voltage and anti-lightning impulse withstand voltage, high breaking current and high mechanics strength etc.
Application:
A fuse cutout combines a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads.
Features:
l Light weight and easy installation
l Reliable fault protection
l Perfect drop out action
l Good hydrophobic property
l Higher creepage distance
Standard:
IEC 60282-1: 2009, IEC 60282-2: 2008, ANSI, etc
