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.
