Huixing Zhongdian(Beijing) Electric Co.，Ltd.was established in 2011 and is located in Wangjing Science and Technology Park, Chaoyang District, Beijing.The company specializes inthe sales and integration services of power transformation，transmission，distribution equipment,power facilities,and related products.With technologyas its core and service as its guarantee, it provides reliable productsand comprehensive solutions for the power system.
The company primarily deals with power transformers, GlS,disconnectors, reclosers, fuses, lightningarresters,insulators,and supporting hardware for highand low voltage transmission and distribution systems, covering substation, transmission,and distribution systems.
The company currently has its headquarters in Beijing, China,as wellas multiple branches in Tianjin, China, Gimpo,South Korea,Arlington, USA,and Santo Domingo,Dominican Republic. Its products are exported to various countries and regions such as South Korea, Indonesia, Vietnam,Dominica, Honduras,and more.The company has established long-termand good cooperative relationships with multiple partnersand has received unanimous praise from users.
Leveraging the industrial advantages of China's power manufacturing industry,we integrate high-qualityupstreamanddownstreamresources,rigorouslyselectreliableproduction partners, and strictly control product quality and technical standards.This ensures that every product delivered tooverseas customers meets international standards,offering both reliabilityand high cost-effectiveness. Simultaneously，we fully leverage our role as a bridge and bond,bridging information gaps and supply chain barriers between domestic and international markets.This allows overseas customers to convenientlyaccess high-quality Chinese power resources without dealing with complex industrial processes.They can enjoy effcient, professional,and hassle-free technical services and product supply，thereby contributing to the high-quality development of the global power industry and achieving mutual benefit and win-win results.
We are committed to providing comprehensive and one-stop docking services for foreign customers,serving as the core bridge for Chinese power products to go global and for foreign demands tobe fulfilled in China.We alwaysadhere to the concept of open cooperationand sincerely look forward toworking togetherwithpartnersfromall over theworldtoexplorenew opportunities in the power sector andbuild a sustainable power future.
Introduction
The Joongwon Recloserisdesigned tomeetincreasing requirementof theelectricutityindustry,providingasafe, maintenance free,longlife,economical device toperform faultcurrentinterupting and reclosingonoverhead distributionlines.TheJoongwonRecloserisapplicableto12/15/17.5kV,24/25.8/27kV,36/38kVpowerdistribution systemsandsubstation.Itcan beoperated manually(ifapplicable)orelectricallyviacontroller withFTUand should be mounted to the pole and substation mounting base.
Features
- Proven design rated for 10,ooo full load operations
- Hydrophobic Cycloaliphatic Epoxy (HCEP) insulation provides industry leading reliability
- Air insulation for an environmentally friendly design
- Minimal maintenance required for the high voltage unit
- Web Human Machine Interface (web HMl software for field configuration
- Remote Communication \because MODBUS,DNP3.0,DNP3.0 oVerCP/IP IEC 60870-5-101,IEC 60870-5-104(option),IEC 60850
Design
Magneticactuators:10,Ooo full loadoperations
Vacuum interrupters:Lasting quality with 10,ooo full load operations
Pole assembly
- UV protected for environmental durability - Molded design reduces risk of tampering
HCEP insulatingmaterial
- The Recloser insulating material is Hydrophobic Cycloaliphatic Epoxy(HCEP). Hydrophobic means resistantto water.This capability isadvantageous because it prevents water from developing completely wetted, resistively conductive surfaces on outdoor insulation.
