Application Of Horizontally Openable High-voltage Disconnectors In 35 Kv

hv isolator occupies an important position in medium and high voltage power distribution systems. In the configuration of 35 kV voltage level transmission lines and substations, the horizontally spread hv isolator switch structure is widely deployed. This type of switch is frequently used because its operation and structural design meet the spatial layout requirements of 35 kV systems.

Structural Adaptability and Installation Convenience

The horizontally pull-out high voltage electrical isolator's pole design and drive mechanism are arranged in a straight line, facilitating its placement in 35 kV switch rooms or outdoor busbar systems.

• Modular Pole: Pole length and support components can be flexibly adjusted according to site layout.

• Mechanical Transmission Efficiency: The horizontal pull rod, combined with manual or electric operating mechanisms, ensures smooth operation and uniform torque distribution.

• Grounding and Insulation Configuration: The height and spacing of the supporting insulators are suitable for 35 kV standards, maintaining stable electrical clearances during long-term operation.

This layout reduces spatial interference with busbars and adjacent equipment, facilitating construction and subsequent maintenance.

Operating Performance and Characteristics

The isolator high voltage horizontally pull-out structure exhibits excellent operating characteristics in 35 kV systems.

• Sectional switch operation:

• The opening speed is matched to the contact separation time, reducing arc impact.

• The mechanical return after contact closure is precise, reducing the probability of malfunction.

• Environmental resistance:

• The switch rod and insulator materials are adapted to outdoor temperature variations.

• The lateral layout reduces the impact of wind load and snow accumulation, ensuring operational stability.

In 35 kV systems, the horizontal opening design of this type of high-voltage disconnector is one of the standard configurations. It meets equipment layout and operational requirements while maintaining a simple structure.
