Product Overview

Generally, it is divided into three types: air insulation, solid insulation and SF6 insulation, which are used for opening/closing load current, breaking short circuit current and transformer no-load current, and charging current of overhead lines and cable lines at a certain distance, which plays a role in control and protection, and is an important switching equipment for ring network power supply and terminal power supply. Load switches with air insulation mainly include air generation type, air compression type and vacuum type. The product categories of ring main unit include HK-10, MKH-10, 8DH-10, XGN-15, SM6, and FOX-HD series.
