Sectional Isolation Type Outdoor Three-Pole SwitchSectional Isolation Type Outdoor Three-Pole SwitchSectional Isolation Type Outdoor Three-Pole SwitchSectional Isolation Type Outdoor Three-Pole SwitchSectional Isolation Type Outdoor Three-Pole SwitchProduct Description

The three-column outdoor load isolating switch is a high-voltage electrical equipment used in power systems. It is mainly used to realize the segmentation, isolation and load switching operations of circuits in outdoor environments. It is widely used in substations, distribution lines and industrial power systems to ensure the safe operation and maintenance of power equipment.
Main features
Outdoor design
It adopts waterproof, dustproof and corrosion-resistant outdoor design, which can adapt to various harsh environmental conditions, such as high temperature, low temperature, humidity, etc.
Three-column structure
It adopts a three-column design, corresponding to three-phase circuits (phase A, phase B, phase C), to ensure the independent isolation and operation of each phase circuit.
Load switching function
It can be disconnected under load, which is suitable for occasions where frequent load switching is required.
Isolation function
It provides reliable electrical isolation to ensure the safety of equipment maintenance or overhaul.
High reliability
It adopts high-quality insulating materials and mechanical structures to ensure long-term stable operation and reduce the failure rate.
Easy to operate
It is equipped with manual or electric operating mechanism, which is simple and convenient to operate and suitable for different scene requirements.

Circuit Breakers & Switch
 /Isolating Switch   LBIS type

General

 LBIS Type outdoor on load break switch disconnector contained in this list are destined to switch stub lines and ring main lines or transformers (It can be equipped with MV HRC fuse links as short circuit protection fuction) or for switching under on load conditions. This disconnector complies with IEC/IEEE and DVE-recommendation standards especially comply with DIN VDE 0670 part 3 and IEC 60265, IEC 129.

 Features

 All steels are made of either in stainless steel or hot-dip galvanized steel.

 1. Solid and stable base frame.
 2. main contact with ice protection.
 3. Polymer insulators or alternatively in porcelain.
 4. Minimal sag for the line-connection between two fixed terminals.
 5. Completely maintence antirust Aluminium alloy Arc chamber.
 6. Switching-off procedure without external arc.
 7. Short circuit making capacity under specific conditions possible
 8. Fixing on the supporting structure either by clamping(free setting) or screwing (holes in the   base frame)
 9. Easy on-site installation and setting.

 10. High reliabilty up to 1000 cycles (depending on the running current).

 11. All contacts are either sliver or tin-plated.
 12. Practically maintance-free.
