SF₆-Free Medium Voltage Switchgear — Made in Korea

A Korean SF₆-free switchgear manufacturer for a post-SF₆ grid

TechPro Co., Ltd. is a South Korean manufacturer of SF₆-free, solid-insulated medium voltage switchgear rated at 25.8 kV (IEC 24 kV class). As utilities worldwide phase out SF₆ — the most potent greenhouse gas — under the EU F-gas Regulation and US (California CARB) rules, our epoxy/polymer solid-insulated technology is a future-proof, cost-competitive alternative to conventional gas-insulated equipment.

Why choose TechPro

• Utility-proven: over 1,000 units installed across 38 KEPCO (Korea Electric Power) substations.
• SF₆-free & eco-friendly: solid epoxy/polymer insulation — no SF₆ greenhouse gas, lower lifecycle/maintenance cost.
• Type-tested to IEC 62271 by KERI (Korea Electrotechnology Research Institute); in-house test facilities (partial discharge, impulse, short-circuit, Hipot).
• Competitive value: Korean build quality at a price below the major brands, with full engineering support.
• Export experience: Taiwan, Pakistan, Zimbabwe, Indonesia.
