A cleaner, more reliable approach to MV switching
The HP-ELS series replaces SF₆ with environmentally friendly insulating media while keeping the proven safety and performance utilities expect from gas-insulated switchgear.
Product Overview
The (YBH)GF-40.5 new-energy photovoltaic (wind-power) box substation — commonly called a PV box substation — applies box-type substation technology in the new-energy field of PV generation. It organically combines PV AC/DC generation systems, inverter units, low-loss transformers and control systems for simplified configuration, high reliability and flexibility, safe and convenient O&M, plus environmental friendliness, energy saving and a compact structure — fully meeting the grid-connection needs of PV stations.
