Quick ViewPRODUCT FUNCTION
Drop out surge arrestors are MOV based devices that are designed to protect against the damaging effects of spikes and transients caused by lightning, utility switching, isolation arching, electrical motor cycling, or any other sudden change in the electrical power flow on incoming AC power lines. Lightning damage, is responsible for a large percentage of over-voltage occurrences, these are either direct strikes to a line or induced voltages onto the line. (strikes within 40m of a line).
Drop out surge arrestors prevent flashover between phases, prevent damage to poles and protect transformers from lightning damage and surges. Live Line Arrestors can be intelligently placed on lines in problem areas where equipment is consistently damaged.
The placing of Drop out surge arrestors has proven to be more cost effective than improving the insulation of poor performing lines. A spent Drop out surge arrestor can be exchanged for a new unit within minutes with the aid of a link stick and with the system energized. This eliminates unnecessary outages and lost revenue for the electrical utility.

Quick View33KV – 36KV Medium Voltage Drop-out Fuse Cutout Switch
Product introduction:
Fuse Cutout with Porcelain Base is mainly used to protect distribution lines and
transformers against overload and short-circuit damage. It can also be an overhead
disconnection switch with the use of a portable load-break tool. The fuse cutout is
developed to fit common service conditions.

Quick ViewNulec W-series
MV Pole-Mounted Automatic Circuit Reclosers
MV reclosers up to 38kV
The W-Series single phase, pole mounted auto recloser or circuit breaker was developed to achieve optimum performance and reliability, making use of the latest technology in solid dielectrics, vacuum interruption, and microelectronics. This device does not use any gas or oil insulants. Instead, a cyclo-aliphatic epoxy bushing is used to insulate the vacuum interrupter. This type of construction results in a more lightweight unit. With an integrated CT and VT, the design is optimised for automation, remote control, data logging and monitoring applications. The W-Series recloser is ideal for Single Wire Earth Return (SWER) applications.
