This three-phase integrated current transformer is vacuum-cast with high-quality epoxy resin and enclosed in a flame-retardant plastic housing. It features excellent moisture resistance, stable electrical performance and requires no routine maintenance. Suitable for 50Hz or 60Hz power distribution systems, the unit delivers accurate measurement and protection for three-phase and zero-sequence currents, and is specially designed for three-phase bushings in ring main units and pole-mounted switches. The rated current ratios and rated loads of its measuring windings and composite windings can be customized to meet specific customer requirements.
