This PDF product flyer targets power utilities, EPC contractors and switch‑cubicle manufacturers for tender comparison, cabinet‑solution selection and pre‑sales technical evaluation. This SF6‑insulated three‑position load‑break switch complies with IEC 62271‑1, IEC 62271‑103 standards.
It integrates closing, isolating and earthing functions within one unit with modular spring‑stored‑energy actuator, achieving up‑to‑5000 overhaul‑free mechanical operations.
This flyer records full power‑frequency & lightning impulse dielectric‑withstand values for phase‑to‑earth, phase‑to‑phase and isolating‑gap; load‑current, cable‑charging, no‑load‑transformer breaking‑capacity, earth‑fault breaking performance, 20kA‑4s short‑time withstand‑current, 50kA peak withstand‑current, 620 mm creepage distance and wide operating‑temperature of ‑40 ℃ ~ +60 ℃.
It is supplied with complete standardized accessories and spare‑parts, supporting custom‑manufacturing including parameter adjustment, accessory configuration and project‑specific factory‑acceptance‑test for ring‑main‑unit, cable‑feeder and secondary‑distribution‑substation projects. Please contact us for dimension drawings and full‑set type‑test‑reports.
