AC Metal-enclosed Switchgear

The 35kV voltage level is the main power line for many large plants and substations. The AC metal enclosed switchgear protects this vital line. It is made for three-phase AC 50Hz systems. It works for single bus and split bus systems. AC metal enclosed switchgear handles power reception, distribution, control, and protection. At 35kV, there is no room for mistakes. Every detail of this unit is built for safety and high performance. For us, AC metal enclosed switchgear is the steel wall for your core assets.

This unit works with top breaker brands. You can choose from Cutler-Hammer, Schneider, ABB, or high-end domestic brands. This gives you flexibility based on your budget and needs. The protection level is IP4X for the hull. Even when the breaker door is open, it stays at IP2X. This keeps operators safe from live parts. The insulation levels are high. The 1-minute power frequency withstand voltage is 95kV. The lightning impulse withstand voltage is 185kV. A common question we get is, "Does it have five-prevention features?" Yes. The mechanical interlocks are strong. They prevent wrong operations like moving the breaker with load on. AC metal enclosed switchgear gives you the last and best line of defense.

We offer full customization for high-voltage systems. You can choose current ratings from 1250A to 1600A. Short-circuit breaking capacity ranges from 16kA to 31.5kA. We can design the main circuit to fit your site. If your site is above 1000 meters altitude, we can make special adjustments. We follow IEC60298, GB3906, and DL/T404 standards. We have full type test reports for your project approval. AC metal enclosed switchgear is used in large industrial plants, regional substations, and industrial park switch stations. Choosing it means choosing reliable protection for your most important assets. We offer an 18-month warranty. Our team is ready to support you.
