Surge Arrestor Separators

Video/radio signal surge protective device is designed according to the IEC standard and national standard. It can be used for single BNC terminal, 16 BNC terminals, F terminal and N terminal lightning protection.

This product is suitable for the monitoring system BNC terminal, matrix BNC terminal, optical transceiver BNC terminal, video camera BNC terminal as lightning surge protection.

This product is produced according to the discharging, clamping, filtering principles, that realized high efficient discharging lightning currents and resistance of EMP shock which caused by lightning currents. It has advantages of multi classesâ?? protection, extremely low residual voltage, perfect transmission performance, quick respond, large discharging capacity, simple installation and connection, easy maintenance.

DK Company can produce this product with different classes working voltage and various number of terminals according to the customer requirement. The 8/20us maximum discharging currents (Imax) can reach 10kA.

Atmospheric events and on-off surges in the system cause formation of
extreme voltages in electricity networks. ELOPAR surge ARRESTORS are designed to protect distribution transformers, engines, work machines and medium voltage cables
against extreme voltages in the best way.
Advantages of Elopar Polymer Surge Arrestors are;
- Low Protection level - No danger of explosion
- Long protection distance- High energy input capacity
Resistant to aging - Stable characteristics
- Polymer housing- Resistant to contamination
- Safe assembly- Maintenance-free
- High support resistance- Easy to use
- Creeping distance is over 25 mm/kV- Light
Structure and Mode of Operation;
Metal oxide surge arrestors do not contain gaps but contain metal oxide blocks that are placed into a polymer body impermeably. These blocks carry variable resistance feature. In other words, they become conductive as the voltage rises. In case of temporary over voltage, current flows over surge arrestor so that such devices or cables are protected.
These surge arrestors not only have a very good mechanical strength, but also have very good dielectrically smoothness in all surfaces. Furthermore, they have high resistance against contamination arising from atmospheric conditions under the heaviest operating conditions.
ELOPAR Polymer Surge Arrestors are manufactured according to TS EN 60099-4 (IEC 60099-4) standard in order to perform this task in the best way.
Type tests have been performed at ICMET CRAIOVA High Power Laboratory and it has passed from all tests successfully.

- Surge arrestors must be as close as possible to the device to be protected.
- Surge Arrestor grounding must be the same with the system grounding
