12KV Wall Bushing (140×200)

The TG3‑12KV/140×200 Wall Bushing is designed for 12 kV medium-voltage systems, with a rated current range of 2500–3150A. It offers a power frequency withstand voltage of 50 kV for 1 minute and a lightning impulse withstand voltage of 110 kV. Constructed with composite insulation of epoxy resin, copper shielding, and silicone rubber, it provides excellent electrical performance and effective electromagnetic shielding. With an IP68 protection level, it features excellent dustproof and waterproof capabilities, making it suitable for harsh working environments.

With an installation size of 140×200 mm (outer diameter × length), this wall bushing is ideal for electrical connections and insulation in medium-voltage switchgear, transformers, and ring main units. Its wide temperature range (‑40℃ to +90℃) ensures stable operation in extreme temperature environments, making it especially suitable for industries like new energy, industrial power, and petrochemicals, where reliability is critical. Whether used indoors or outdoors, it ensures stable system operation and provides an efficient electrical connection solution.
