Benefits of Product Application

Suitability for application in areas with low temperatures 

The design of solid ring main unit reduces the dependence on SF6 gas which eliminate the potential problem caused by insulation gas of being liquefied under low temperature

Suitability for application in areas with high temperatures

The increased pressure caused by higher temperature is no longer an issue for solid dielectric ring main unit

Suitability for application in low-lying areas and construction sites with labor forces

The density of SF6 is five times more than normal air under the same condition, leaked SF6 are easily deposited in low-lying areas which is very dangerous for people working there. People can be suffocated by leaked gas.  

Suitability for application in closed environment:

Vacuum arc extinguishing chamber is under normal pressure where all bushing and sealed fillings are solid dielectric which prevent the potential of explosion caused by normal gas insulated product.

Suitability for frequent switching operation

SF6 load switch is designed for switch operations for up to 2000 times, while the switch operations for solid dielectric designed ring main units are more than 100000 times.

Suitability for environmental protection

The green house effect caused by SF6 has drawn much attention, solid dielectric designed ring main unit eliminate the use of SF6 gas, which further meet the national requirement for environmental protection.

Specification

We have focused on the research and development of completely sealed ring main units for 15 years. In order to develop advanced, high-tech, secure and easily used products, we have always looked for new and revolutionary ideas and designs. We can therefore maintain our dominant position at the forefront of the market and meanwhile best serve our customers.

The quality, reliability and prompt delivery of our products is guaranteed by the excellence of our employees and our own factories. Our core work team consists of several highly educated, experienced and advanced personnel. We have our own product manufacturing, testing, producing, sheet-metal machining and cable accessory processing bases. These facilities offer both customization services and direct production control that guarantees quality standards.

With all of our research, production and testing procedures meeting both national and international standards, we now supply products in seven categories. For these series, we have been awarded an international invention patent, two national invention patents and a patent for five utility technologies.

Our new model solid insulation sealed ring main unit has been developed under the support of related national departments. Utilizing advanced pole insulation techniques and epoxy resin and silicone seals, these products took two years and seven months to develop, and have been awarded seven patents.

In April, 2012, Solid Insulated RMU developed by SOJO Electric has successfully passed Full Type Test at KEMA in accordance with relevant International IEC Standards, once again providing the solid support to the excellent performance and reliability of the product.
