Description

Product Description

Busbar support porcelain insulators are essential components in electrical power systems, designed to provide both mechanical support and electrical insulation for busbars—conductive bars that distribute electricity within switchgear, substations, and industrial equipment. Crafted from high-quality porcelain, these insulators prevent current leakage between busbars and grounded structures, ensuring safe and efficient power distribution even in high-voltage environments.

Main Feature

Dual Functionality: Combines robust mechanical support to hold busbars securely in place with reliable electrical insulation, preventing short circuits and ensuring system safety.
High Insulation Strength: Made from dense porcelain material with excellent dielectric properties, capable of withstanding high voltage levels without breakdown.
Mechanical Durability: Resistant to mechanical stress, vibration, and thermal expansion, maintaining stability in demanding industrial and substation settings.
Weather and Corrosion Resistance: Unaffected by moisture, dust, and chemical exposure, making them suitable for both indoor and outdoor applications.
Compliance with Standards: Manufactured to meet industry specifications, ensuring compatibility with various busbar systems and power distribution setups.

Faults and Handling of Single-phase Grounding in 10kV Distribution Lines

Characteristics and Detection Devices for Single-Phase Ground Faults1. Characteristics of Single-Phase Ground FaultsCentral Alarm Signals:The warning bell rings, and the indicator lamp labeled “Ground Fault on [X] kV Bus Section [Y]” illuminates. In systems with a Petersen coil (arc suppression coil) grounding the neutral point, the “Petersen Coil Operated” indicator also lights up.Insulation Monitoring Voltmeter Indications:The voltage of the faulted phase decreases (in

Neutral point grounding operation mode for 110kV～220kV power grid transformers

The arrangement of neutral point grounding operation modes for 110kV～220kV power grid transformers shall meet the insulation withstand requirements of transformer neutral points, and shall also strive to keep the zero-sequence impedance of substations basically unchanged, while ensuring that the zero-sequence comprehensive impedance at any short-circuit point in the system does not exceed three times the positive-sequence comprehensive impedance.For 220kV and 110kV transformers in new constructi

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?

Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I

Understanding Transformer Neutral Grounding

I. What is a Neutral Point?In transformers and generators, the neutral point is a specific point in the winding where the absolute voltage between this point and each external terminal is equal. In the diagram below, pointOrepresents the neutral point.II. Why Does the Neutral Point Need Grounding?The electrical connection method between the neutral point and earth in a three-phase AC power system is called theneutral grounding method. This grounding method directly affects:The safety, reliabilit
