High Electrical Insulation Performance<\/h3>\n\n\n\n

The product is manufactured using an integrated epoxy resin casting process. Its smooth, uniform surface helps minimize bubbles, voids, and insulation defects.<\/p>\n\n\n\n

The high dielectric strength effectively separates live conductors from grounded components, helping reduce the risk of electrical tracking, flashover, and short circuits.<\/p>\n\n\n\n

Accurate Compatibility with 1.2-Metre Switchgear<\/h3>\n\n\n\n

The structure and mounting positions are optimized for 1.2-metre 35 kV switchgear.<\/p>\n\n\n\n

The preformed mounting holes correspond with compatible cabinet structures, allowing the product to be installed or replaced without additional drilling or machining.<\/p>\n\n\n\n

Reliable Mechanical Stability<\/h3>\n\n\n\n

The L-shaped support structure provides good resistance to bending, impact, and deformation.<\/p>\n\n\n\n

It can withstand short-circuit electrodynamic forces and the mechanical stresses generated during long-term switchgear operation, helping maintain the position and stability of busbars, contact boxes, and other internal components.<\/p>\n\n\n\n

Resistance to Environmental Conditions<\/h3>\n\n\n\n

The epoxy resin material offers good resistance to high and low temperatures, moisture, ageing, and chemical corrosion.<\/p>\n\n\n\n

It is suitable for indoor substations, industrial plants, transport power systems, and other demanding indoor electrical environments.<\/p>\n\n\n\n

Improved Operational Safety<\/h3>\n\n\n\n

The red surface makes the insulating component easy to identify during installation, inspection, and maintenance.<\/p>\n\n\n\n

Rounded edges help reduce the risk of accidental scratches and handling injuries while supporting compliance with electrical equipment safety requirements.<\/p>\n\n\n\n

Long Service Life and Low Maintenance<\/h3>\n\n\n\n

The selected insulating material offers reliable resistance to ageing, cracking, and long-term electrical stress.<\/p>\n\n\n\n

Under normal operating conditions, the product can provide a service life compatible with the switchgear assembly, with minimal routine maintenance requirements.<\/p>\n\n\n\n

    The product must be used within the specified voltage and current parameters of the complete switchgear assembly.<\/p>\n\n\n\n

    \u5b89\u88c5\u8981\u6c42<\/h3>\n\n\n\n

    Before installation, clean the mounting surface inside the switchgear. Remove oil, dust, moisture, metal particles, and other contaminants.<\/p>\n\n\n\n

    Install the product using suitable bolts and tighten them according to the switchgear assembly specifications.<\/p>\n\n\n\n

    The fastening force must be applied evenly. Excessive or uneven tightening may produce installation stress and cause cracking or deformation of the insulating component.<\/p>\n\n\n\n

    After installation, inspect the electrical clearance between the bending plate, live components, grounded parts, and the switchgear enclosure. Confirm that all clearances meet the applicable requirements for a 35 kV system.<\/p>\n\n\n\n

    The product must not be installed, removed, or adjusted while the equipment is energized. All work must be completed according to the required power isolation, grounding, and high-voltage safety procedures.<\/p>\n\n\n\n

    Inspection and Maintenance<\/h3>\n\n\n\n

    The product requires minimal routine maintenance under normal operating conditions. However, its condition should be inspected during scheduled switchgear maintenance.<\/p>\n\n\n\n

    Inspection items include:<\/p>\n\n\n\n

      \n
    • Surface cracks<\/li>\n\n\n\n
