RHG-145 GIS: 145kV, standard rated normal current for T&D substations. Lightning impulse, short-time withstand and making current match 145kV class. Self-blast interrupter for 145kV transmission-distribution substations.
RHG‑145 features modular construction with uniform‑size flange joints, min. bay width 800 mm, in‑house three‑position switch, self‑blast interrupter with spring mechanism and double‑seal‑ring. Key parts manufactured by imported process equipment, suitable up to 4700 m altitude, KEMA full type‑test certified per relevant IEC GIS standards.
550kV Ultra-High Voltage Gas-Insulated Switchgear (GIS) features gas insulation, compact design, and top reliability.
ZF-420/4000-63 GIS 420kV SF6-insulated switchgear. 650/1425kV insulation, 63kA, 4000A, <5pC PD, horizontal CB, spring mechanism.
145kV High-Voltage Gas-Insulated Switchgear (GIS) features compact design and gas insulation for reliability.
It has passed complete KEMA full type‑testing to satisfy international insulation and performance requirements complying with relevant IEC standards for GIS.
Uniform‑dimension flanged joints and modular components support flexible configuration for substation optimization; minimum bay width reaches 800 mm to effectively reduce substation floor space.
Double‑sealing‑ring structural design is applied on flange joints, which ensures low SF₆ leakage rate and long‑term gas‑tight integrity inside the gas compartments.
