12‑24 kV SF6‑insulated three‑position load‑break switch, 630‑4000A rated current, 20‑40kA short‑circuit withstand, modular spring‑actuator, 5000 overhaul‑free mechanical cycles, for medium‑voltage ring‑main‑unit & distribution switchgear.
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.
SF6 insulated 3-position load break switch for 12kV and 24kV, enabling safe switching, isolation, and grounding in MV distribution networks.
Outdoor sectionalizing vacuum load break switch for 12kV lines, enabling safe isolation of faulted sections to restore power quickly.
SF6 insulated 3-position load break switch: reliable, compact and IEC compliant. Ideal for medium-voltage distribution grids. Direct from manufacturer.
Focus on rated load‑breaking, cable‑charging breaking, no‑load‑transformer breaking and earth‑fault breaking capacity to match actual feeder‑load conditions. Please contact us for load‑matching‑checklist.
Confirm rated‑current, short‑time withstand‑rating, various breaking‑capabilities, mechanical‑life, cabinet installation‑dimension and interlock‑logic compatibility. Please contact us for retrofit‑assessment support.
Custom‑available items include rated‑parameter tuning, accessory‑combination optimisation and project‑specified factory‑acceptance‑test‑items. Please contact us to submit your technical‑specification.
