  • Product Description

  • Product Overview

    Insulating protective covers are commonly used protective devices in power systems. They are primarily made from insulating materials such as silicone rubber and are designed to encase various types of electrical connectors, busbars, and terminal blocks. These covers isolate live components from the external environment, reducing safety risks caused by accidental contact, foreign object bridging, or environmental corrosion, thereby helping to enhance the operational stability of power equipment.

    Product Features

    1. Stable insulation The material features sustained electrical insulation performance, which can reduce risks such as electric shock and short circuits.
    2. Clearly distinguish the appearance. Some models feature a three-color design—red, yellow, and green—corresponding to the three-phase markings of power systems, making it easier to identify and standardize wiring on-site.
    3. Weather-resistant and durable It is resistant to the erosion of ultraviolet radiation, acid rain, and everyday dust, thereby slowing down the aging process of power connectors and busbars.
    4. Wide compatibility It covers various structures such as T-shaped, cross-shaped, and straight-line types, making it suitable for different layouts of power connection points.
    5. Easy to install It features an open-and-close or snap-lock design, allowing for easy wrapping and securing without the need for complicated tools, and is compatible with various specifications of electrical connectors.
    6. Flexible and snug-fitting The material has excellent flexibility, allowing it to conform to the shape of the joint and adapt to various installation layouts.

    Product Applications

    • Insulation protection for cable T-type/cross-type branch connectors and transformer bushings
    • Protection of busbars and terminal blocks inside high- and low-voltage switchgear and distribution boxes
    • Joint protection for outdoor switchgear, ring main units, and other equipment
    • Insulation protection for electrical connection points in industrial environments such as chemical and metallurgical industries.
    • Protection and supporting equipment for urban power grid upgrades and distribution systems in new energy power stations.
