Product Description
Three-phase Combination Type Lightning Arrester a new type arrester to protect electric appliance from the damage of overvoltage. The characteristic is that it limits the overvoltage between phase and earth. At the same time, it effectively limits overvoltage between phases. Common lightning arrester can’t do it.

Product Feature
1.New unique structure 2.Four-element Star Connection 3.Good technical performance 4.Insulation 5.High voltage resistance 6.Make full use of using space 7.After Overall molding, the composite housing has good sealing, anti-explosion and damp proof performance. And it’s also good in damp proof, leak resistance, electrical erosion resistance, stain resistance and hydrophobicity. 8.Its high voltage cable wiring ensures the insulated strength and flexible installation. 9.With small volume, light weight, it saves occupied area. It’s exclusively suited for all kinds of switch cabinet (horizontal installation and vertical installation available).

Product Specification/Models
Using Selection: Three-phase Combination type Surge arrester divides into two types: gapless type & parallel series clearance/gaps. The difference is that as long as there is overvoltage in the system, gapless type surge arrester can effectively absorb and limit it; while for the parallel series clearance surge arrester, only when the overvoltage of the system is big enough to make discharge, it acts.

Other Information
It’s widely used to protect vacuum switch, rotary motor, parallel capacitor, power plant and substation and etc. It has been over ten years since such combination type surge arrester started to run. The protective role of one combination type lightning arrester plays equals to that of 6 common surge arresters. Because it adopts high capacity ZnO varistor as main components, its volt-ampere characteristics and capacity of adsorbing overvoltage are both good. So it may offer reliable protection to the electric appliance. It’s very popular in the power system.
