1. Features
LW36-126/145 Type outdoor self-blast HV SF6 circuit breaker is widely used in 50Hz, 126/145 kV (Max) power system with altitude less than 3000 m, air pollution below Level IV. It is used to break rated current, fault current or switch electric lines, to realize the controllig and protection of power system. It can also be used as connecting circuit breaker.
This type of circuit breaker uses SF6 as arc extinction and insulation medium. It adopts the world's leading self-blast arc extinction technology. It is featured by long service life, low operating power, low noise and high reliability. It matches the oil-free and large capacity development trend in power equipment industry.

Zhejiang Jiangshan Transformer Co., Ltd. (Previous name Jiangshan Transformer Factory in Zhejiang province) is the professional manufacturer of the power transformers grade 230-500kV and below. Appointed by the Ministry of Mechanical Industry, it has been titled as a National class 1 Company because of the innovative technology employed. JSB is a well-known company in the Zhejiang Province. Our factory is equipped with very convenient transportation condition. It is located near both the railway Zhe-GaN, and National road No. 205, This means that JSB is located only-40km from Quzhou airport. Our factory is a large company, employing over 500 staff, of which 35% hold college degrees. It covers around 230000m2, With the construction area being over 67000m2. In 2009, fixed assets of our factory has reached 320 million Yuan. Our JSB has over 40 years experience in transformer design and production. It has a well equipped assembling line and testing machines that are able to provide first-class products and services. As such, JSB's main products are:
500kV grade and below power transformer, entire sealed transformer, dry transformer, amorphous alloy transformer, combination transformer, and other particular transformers used in electrical furnace, mine, thunder. Proof, or extinction, single phase, and current, voltage transducers and so on, it could provide over 60 series, 800 types, and 2000 specified transformers. Its annual capacity is 1800 million kVA. Its products have been sold to Zhejiang, Jiangxi, Fujian, Jiangsu, Hubei, Hunan, Yunnan, Xinjiang and so on. At the same time, our product is also very well-known overseas. We have many well-satisfied foreign customers from over 30 countries and regions such as Southeast Asia, Africa, South America, Oceania and Russia, Mongolia and so on. Now Jiangshan practices ISO9001, and ISO14000. Our main products have been awarded Grade One 16 times consecutively, have been tested by National Transformer Quality Supervision Center, and have been awarded as Ministerial Excellent Products. It is recommended by the National Economic and Trade Committee for the upgrading of the national power network.
In 2003, Jiangshan was changed into a subsidiary whose share holder is Zhejiang Guo Guang Technology Group. The chang made Jiangshan more dynamic and brought about a stronger economic background. The more flexible management system will bring better products and services which will satisfy the increasing needs of new and loyal customers, we also manage the products such as cable, GIS, Circuit Breaker, Switchgear etc of sister companies, and also do EPC for substation and transmission line, JSB become a total electricity solution provider.
