Product Overview of Silicone Shield for Electrical Equipment Accessories
Silicone protective cover for electrical equipment accessories is an electrical protection device made of silicone rubber as the core material, which has the characteristics of high temperature resistance, corrosion resistance, and strong insulation. It is widely used in high and low voltage electrical equipment, and can effectively prevent equipment failures caused by short circuits, leakage, and external factors, ensuring the safe operation of the power system. Its design complies with the national GB12168-90 standard for live working covers and has been tested and qualified by authoritative institutions such as the National Wire and Cable Quality Supervision and Testing Center.
Core characteristics and technical indicators of silicone cover
Material and performance advantages
Material characteristics: Made of high-quality silicone rubber (including imported raw materials), it has transparent substrate coloring properties and is produced through HTV solid-state high-temperature vulcanization molding process. It has high elasticity, toughness and hydrophobicity, excellent weather resistance, and can resist UV rays, acid rain and chemical gas corrosion.
Temperature resistance range: Suitable for ambient temperatures ranging from -60 ℃ to 380 ℃, able to work for a long time at high temperatures of 200 ℃, without heat shrink bonding issues, and still maintain flexibility in low temperature environments.
Insulation and safety performance: Insulation strength ≥ 20KV/mm, power frequency withstand voltage up to 42kV/min (10kV rated voltage products), flame retardancy LOI 35%, effectively blocking the risk of exposed live parts, mainly applicable to equipment and scenarios
Core application areas: Terminal protection for equipment such as distribution transformers, lightning arresters, outdoor switches, busbars, insulators, motor contacts, and high-voltage copper components.
Special protection scenarios: prevent wet flashes, pollution flashes, salt spray corrosion, as well as short circuit accidents caused by small animals such as mice, birds, and snakes coming into contact with charged bodies, reducing the risk of power outages and equipment damage.
Functional value embodiment
Safety guarantee: Avoid human contact with electric shock, foreign object overlapping and short circuit, reduce power accidents caused by electricity theft and natural disasters, and minimize economic losses.
Convenience of operation and maintenance: The buckle structure design supports quick installation and disassembly, does not affect the daily maintenance of equipment, and is compatible with various specifications of terminal posts.
Market Applications and Typical Cases
Industry practice: State Grid Chaoyang Power Supply Company uses it for overhead power lines to improve the insulation level of transmission lines, known as the "Little Red Riding Hood" insulator protection cover.
Product form expansion: Various types have been derived, including snap on protective sleeves, busbar insulation sleeves, heat shrink covers, etc., to meet differentiated protection needs such as transformer pile heads and cable joints

1. Dimensional drawings or samples of products
2. Product hardness color requirements (no relevant information we will be customized according to conventional industry standards for you)
3. The quantity requirements of the product (the more the relative number of customized goods, the more cost-effective)
4. The time of product production and processing (the time is related to the number of products and whether the mold is opened. The normal time is 3-10 days)
Rubber material description:
Silicone (VMQ): high temperature resistance, non-toxic, good water resistance, oil resistance general temperature resistance (-60~350) Butanning rubber (NBR): good oil resistance, good sealing effect, temperature resistance (-50~120) fluorine adhesive (FPM): wear resistance, high temperature resistance, oil resistance, corrosion resistance, good aging resistance, Temperature resistance (-20~300) EPDM: good aging resistance, poor oil resistance, temperature resistance (-50~150) Natural rubber: good elasticity, good alkaline resistance, poor oil resistance, temperature resistance (-30~110)
