Application Scenarios

  • Wind & solar PV renewable collector substations, urban underground distribution vaults, commercial high-rises, and industrial plant ring feeds.

Features

  • Hermetically sealed 3.0mm 304 stainless steel gas tank protects all live high-voltage components against flooding, humidity, dust, and aggressive industrial fumes (IP67).
  • Modular flexibility supporting extensible and compact non-extensible configurations (CVC, CCV, CCF, V, C, F) for smart ring distribution networks.
  • Maintenance-free vacuum circuit breaker (VCB) and 3-position disconnect/earthing switch with mechanical interlocks for foolproof operator safety.

Standards

  • Type-tested to IEC 62271-200:2021 with certified routine test reports (FAT), gas tightness certification, and 100% X-ray weld inspection.

100% Factory Acceptance Testing (FAT) Protocol

CNAS Certified
