Surge arrester scope of application
AC gapless metal oxide surge arresters are used to protect the insulation of AC power transmission and transformation equipment from lightning overvoltage and operating overvoltage damage. It is suitable for over-voltage protection of transformers, power transmission lines, power distribution panels, switch cabinets, power metering boxes, vacuum switches, parallel compensation capacitors, rotating electrical machines and semiconductor devices. Taporel Electrical Insulation Technology Co., Ltd. is a great company that can provide you with Great Surge Arrester.
Surge arresterâ??s Features and principles
The AC gapless metal oxide arrester has excellent nonlinear volt-ampere characteristics, good response characteristics, no freewheeling, large current capacity, low residual voltage, strong suppression of overvoltage, pollution resistance, anti-aging, and no altitude constraints. Simple structure, no gap, tight sealing, long life and other characteristics.

With a strong production capacity, the company can meet high-volume orders, providing customizable options for global clients.
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 overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to melt, disconnecting the transformer from the line. It can also be opened manually by utility linemen standing on the ground and using a long insulating stick called a "hot stick".
Wholesale Fuse Cutout â??s Construction
The fuse elements used in most distribution cutouts are tin or silver alloy wires that melt when subjected to high enough current. Ampere ratings of fuse elements vary from 1 ampere to 200 amperes.
Standards
Up until the mid-1990s each manufacturer used their own dimensional standards for cutout design; by the late 1990s most cutouts were of an "interchangeable design". This design allows for the interchangeable use of cutout bodies and fuse holders manufactured by different vendors.
