PRODUCT OVERVIEW
According to the requirements of the standardized customized scheme of the environmental protection gas insulated ring network cabinet, the vacuum interrupter is used to open and close the circuit. Switch insulation parts are mostly recyclable and environmentally friendly thermoplastic clinker, with a recovery rate of more than 90% in the product life cycle. The gas insulating medium can use nitrogen or dry air as the insulating medium to meet the environmental requirements.
