1. Product introduction
This is an indoor fixed 10 kVhigh-voltage ring, which utilizes a combined switch-fuse circuit. It features a compact design, economical cost, and high reliability. It is primarily used for ring grid power supply, terminal power supply, and distribution and protection of electricity in distribution networks.
With the advantages of small size, low cost, easy operation and no maintenance, it is the main medium voltage power distribution equipment for urban and rural power grids, residential areas, industrial parks and box-type substations.
