Product Description

Product Advantages

1. Fire-safe Design · Oil-free & Highly Reliable

Epoxy-resin cast and oil-free design eliminate leakage and fire risks. Flame-retardant, moisture-proof, and dust-proof features ensure safe operation in hospitals, commercial centers, and metro stations.

2. Low Loss & Low Noise · Energy Efficient

High-grade silicon steel and optimized magnetic circuits reduce losses and noise. Meets or exceeds IEC/GB efficiency standards, with optional low-loss designs to minimize operational cost.

3. Strong Short-circuit Withstand · Thermal Stability

Vacuum casting ensures strong mechanical strength to withstand short-circuit forces and high temperatures. Class F/H insulation maintains stable performance under heavy-load or harsh environments.

Product Advantages

4. Very Low Partial Discharge · Long Service Life

Advanced insulation and strict PD control ensure extremely low partial discharge, slowing insulation aging and enabling 20–30+ years of reliable service life.

5. Maintenance-free · Flexible Installation · Low Cost

Oil-free and maintenance-free, with multiple protection levels (IP00/20/23). Can be installed close to load centers, reducing cable cost. Compact design facilitates easy installation.

6. Wide Voltage Range · Multiple Models · Fully Customizable

Available in 6–35kV with SCB10/11/12 and SCZB10 models. Customizable based on load, ambient temperature, altitude, and noise requirements for perfect project matching.
