  • We are a factory specializing in the production of outdoor 1250A 12kV vacuum interrupters. The vacuum interrupters customized by 777 Electrical Technology Co., Ltd. have long service life, energy saving, material saving, fire prevention, explosion-proof, small volume, long service life, low maintenance cost, reliable operation and no pollution. We look forward to becoming your long-term partner in China.

  • We are a factory specializing in the production of Embedded Pole For Circuit Breakers,Since epoxy resin can be used instead of insulation and mechanical support, the circuit breaker becomes compact and simple, and can be used in humid and dusty conditions.We look forward to becoming your long-term partner in China.

  • We are a factory specializing in the production of 12kv Embedded Pole,Because epoxy resin can replace insulation and mechanical support, the circuit breaker becomes compact and simple, and can be used in humid and dusty conditions. When the external insulation of the micro chamber in the air conditioner can not meet the specification requirements, the solid sealing pole is introduced.We look forward to becoming your long-term partner in China.

  • We are a factory specializing in the production of Embedded Pole For Vacuum Interrupter,It is made of epoxy resin by advanced automatic pressure gel (APG) technology. Its appearance, mechanical and electrical properties are good. Through APG technology, the miniaturized ultra-low resistance vacuum interrupter and other components of the main circuit are directly wrapped in epoxy resin.We look forward to becoming your long-term partner in China.

  • We are a factory specializing in the production of 1250A Embedded Pole For Circuit Breakers,Selection of high toughness epoxy resin, with excellent mechanical properties and excellent electrical properties. Use lower reaction of active formula system, fast curing of material, low internal stress of product, to maximize the mechanical properties of the product. Add active micro silicon powder, use epoxy resin material with automatic pressure gelating technique APG (casting).We look forward to becoming your long-term partner in China.

  • We are a factory specializing in the production of 630A vacuum interrupter embedded pole,It is applicable to the construction and transformation of urban power grid, rural power grid, mine, railway and other power grids.We look forward to becoming your long-term partner in China.
