1. Switchgear should be positioned according to project drawings. For long rows (10+ sets), installation should start from the middle.
2. Use cranes or forklifts; do not use roller crowbars.
3. Pull out the circuit breaker handcart and store it properly before installation.
4. Level the foundation; the unevenness must not exceed 2mm.
5. Weld firmly to the foundation channel steel or use anchor screws.
Our production facilities utilize vacuum box helium leak detection systems and local discharge test laboratories. Products are tested according to international IEC standards and are certified under ISO9001, ISO14001, and OHSAS18001 systems.
