Product Description<\/h2>\n

WANGYUAN Post-type Disconnector are designed for visible circuit isolation on overhead distribution lines and substations. Made of high-strength ceramic insulators or composite silicone rubber with hot-dip galvanized steel frames and copper alloy contacts, the robust blade-type switching mechanism ensures reliable make-break operation under load conditions. Available in single-phase and three-phase configurations with manual or motorized actuation, all products comply with relevant international standards, widely deployed in utility pole-mounted and substation isolation applications.<\/p>\n

Note: The LBS type on load break switch (Switch disconnector) is equipped with stored energy released by fuse strike pins.
\nThe stored energy mechanism for the opening oparation is released by fuse strike pins.
\nThe trip actuator is mounted on top of the fuse contact clip.
\nThe DIN type fuse is held in spring type contacts, secured by a tailever. All the components are made of stainless steel, to preventcorrosion have Jong live, and in the rest position. The trip lever is parked in an over-centre position.<\/p>\n

Advantages<\/h2>\n
\n
\n
\n \"Isolation\n <\/div>\n

Isolation Performance<\/h3>\n

The visible break blade design provides clear open\/closed position indication for operational safety. High-quality copper alloy contacts with wiping action ensure low contact resistance and reliable current transfer.<\/p>\n <\/article>\n

\n
\n \"Mechanical\n <\/div>\n

Mechanical Strength<\/h3>\n

Hot-dip galvanized steel frames and mounting brackets withstand severe mechanical loads and short-circuit forces. Ceramic insulators offer high compressive and cantilever strength for long-term structural integrity on poles.<\/p>\n <\/article>\n

\n
\n \"Weather\n <\/div>\n

Weather Resistance<\/h3>\n

Ceramic insulators with glazed surface resist tracking, erosion and UV degradation in outdoor environments. Hot-dip galvanized steel components provide decades of corrosion protection in harsh climatic conditions.<\/p>\n <\/article>\n

\n
\n \"Installation\n <\/div>\n

Installation & Range<\/h3>\n

Compact post-type design simplifies pole mounting with standard bracket interfaces. Motorized actuator option enables remote SCADA-controlled operation, supporting both single-phase and three-phase line configurations.<\/p>\n <\/article>\n <\/div>\n \n
