LW36-40.5 is a outdoor three-phase high-voltage AC equipment that should be placed below altitude of 3000m, environment temperature: no less than -30℃. Pollution class: no more than AC 50Hz in 4th level district. Maximal voltage: 40.5kV. It is suitable for the protection of power plant, transformer station, HV transmission and distribution  of mine industry corporation, as well as be connection breaker.

The product take SF6 gas as arch-suppression and insulation material, adopt the most advanced tech of thermal expansion, auxiliary gas-pressure self-extinguish and new type of spring operation mechanism. It has a stronger electric endurance,little operation power, high reliabilty, high insulation-level, medium price.

Product feature

1 At present the newest self-extinguish arc-suppression  tech as  is used in area of medium-voltage: thermal expansion and auxiliary compressor self-extinguish arching technology.

2 excellent breaking function : it needn't repaired under full capacity ３１.５ｋA for 21 times, needn't change Sulphur hexafluoride, adopt in some condition with high capacity.

3  Currency on capacitor bank is 630A without re-ignite, 50A cable without repeated breakdown.

4 excellent electric property and mechanism reliability to meet with  uesers's demand on less maintenance under continuous operation.

5 parts of new type spring operation mechanism has few amount, long mechanical life, high reliability and low noice, all of which are applied for frequent operation.

6 light spring operation mechanism adopt integral cast aluminium frame

opening or closing spring whose type is rotating pressed spring use method of centralized arrangement. Their structure is compact and anti-fatigue. 

7 suitable for latitude of 3000m or 4th class pollution district.

8 all revealing parts are made from stainless material and their suface are galvanized with strong anticorrosion.

9 credible sealing structure to keep annual leakage rate below 0.5％。

8 it can annex with CT inner or outer, grade of precision can be up to 10.enable to append CT interior and exterior,accuracy an be reach class of 0.2 or 0.2s, each phase of product can equiped with two or four current transducer.
