Document description

This PDF product catalogue is used for secondary‑distribution‑substation tender comparison, equipment‑selection and pre‑sales technical evaluation. This integrated fully‑air‑insulated medium‑voltage switchgear complies with IEC 62271‑1, IEC 62271‑100, IEC 62271‑102 and ANSI‑relevant standards. It adopts epoxy‑resin cast housing with vacuum interrupters, using pure‑air or nitrogen as insulating medium, integrating circuit‑breaker, line disconnector and earthing‑switch within single vertically‑layered modular assembly. This catalogue records full dielectric‑withstand values, O‑0.3s‑CO‑15s‑CO operating‑sequence, opening‑closing‑arcing‑time parameters, E2 electrical‑endurance for breaker, M2‑10 000 mechanical‑operations for breaker module, C2 capacitive‑current breaking performance, M0 mechanical‑class for disconnector and earthing‑switch, phase‑center distance 230 mm, operating‑temperature range ‑15 ℃ ~ +40 ℃, maximum installation altitude up to 3000 m, outer dimension data and complete multi‑level non‑bypassable mechanical‑interlock logic including breaker‑disconnector, disconnector‑earthing‑switch and cabinet‑door interlock. It features lifetime‑sealing structure over 30‑year sealing guarantee, plug‑and‑play accessory compatibility, local‑manual / remote‑electric dual‑control for spring‑trip‑free operating‑mechanism, anti‑pumping protection function. Custom‑manufacturing service covers design adjustment, assembly and project‑specific factory‑acceptance‑test for compact‑substation, overhead‑cable‑protection, capacitor‑bank‑switching and motor‑protection‑projects. Please contact us for complete dimension drawings and full‑set type‑test reports.
