ZW32-24 type outdoor pole-mounted HV vacuum CB (hereinafter referred to as CB) is rated voltage24kV, 50Hz three-phase AC outdoor power distribution equipment used for power distribution network to break and close load current, over-load current and short-circuit current in electric systems. It is used in substation and industrial & mining enterprise power distribution system for protection and control, better fits countryside power grid and frequent operation places, especially for the retrofit of urban power network and countryside power network. Characteristic:
The CB applies three-phase pole-type structure. It has characteristics of stable closing/breaking property, no fire or explosion danger, maintenance-free, small dimension, small weight, long service life, etc.
The CB is hermetical sealed, and is moisture-resistant, anti-condensation. It is especially suitable for application at severe cold and damp areas.
Three-phase pillar and current transformer apply imported outdoor epoxy resin solid insulation materials. It is high/low temperature resistant, UV-resistant and anti-ageing.
The operating mechanism is miniature spring operating mechanism with low breaking/closing energy consumption. The driving of it applies straight transmission with little components and high reliability. The operating mechanism is enclosed in a cabinet, and that makes it rust-resistant and more reliable.

This type insulation piercing connectors are suitable for all types of LV-ABC
conductors as well as connections to service and lighting cable cores.
When tightening the bolts, the teeth of the contact plates penetrate
the insulation and establish a perfect contact.
The bolts are tightened until the heads shear off.
Stripping of insulation is avoided. Suitable for aluminum and copper conductors and
components not losable, end cap attached to body, Insulation material made of
weather resistant glass fiber reinforced polymer,
contact teeth made of tinned brass or copper or aluminum,
bolt made of dacromet steel.

1. This series switch have normal and anti-pollute two difference
models, it composed of frame,support insulator,
with power part and operating mechanism.
2. Each pole have two pieces blade, there is press spring near
the contactor base and have adjusted nut to keep good contact
press, there is a support structure on the blade,
it can be locked after closing, so it will not be closing by itself
under any condition, under normal or short-circuit condition,
it can ensure the reliable performance of dynamic and thermic
stability.
