Environment-compatible switch gear
Features
We offer 24 KV environment-compatible gas insulation switch gear that realizes space saving (55% vs. conventional volume) without using SF6 gas. Increased maintainability and reduction of environmental impacts are achieved while maintaining performance at the conventional level.
METAWATER will continue to supply eco-friendly power receiving and transforming equipment in the future.
- Preservation of the global environment
We never use SF6 gas, which has a global warming effect that is 23,900 times higher than that of CO2. - Space saving
Space saving (55% vs. conventional volume) is realized based on the design, which deploys technology involving a combination of dry-air insulation and solid insulation. - High maintainability
T-shape cable terminals are used. Maintenance and inspection are easier to carry out since a withstand voltage test can be performed without gas treatment being needed.
