Silicone Rubber Anti-Pollution Flashover Booster Shed
Silicone Rubber Shield for Porcelain Insulators can used to protect the 10-1000kV overhead power line insulators (such as pin porcelain insulator, cap and pin type suspension insulator) from bird damage, lightning attack, etc.

Silicone rubber anti-pollution flashover booster shed is made of high-temperature vulcanized silicone rubber, hydrophobic materials, and other insulating materials through a molding process. It is installed on the porcelain, glass insulator or bushing of the power transmission and distribution equipment and is bonded to the upper surface of the shed of the original porcelain, glass insulator or bushing through the special adhesive glues to form an integral body to form a composite external insulation structure. It further increases the specific creepage distance of insulators or bushings and makes use of the excellent Hydrophobicity and Hydrophobic mobility of silicone rubber to make up for the wettability of porcelain and glass surfaces, improve the insulation strength and pollution flashover voltage of insulators and bushings under wet and dirty conditions, and achieve the effect of pollution flashover prevention.
  • Advantages of Silicone Rubber Anti-pollution Flashover Booster Shed

    The insulators or bushings after the installation of the booster shed are like a protective umbrella on the surface of the power equipment, which can effectively improve the anti-pollution flashover capability of the power equipment.
    1. Our booster shed has excellent hydrophobicity, anti-corona, anti-tracking, corrosion resistance and so on.
    2. It is widely used, flexible in use, easy to use and suitable for various environments.
    3. It can be used as various porcelain or glass insulators for power equipment, such as ordinary and anti-pollution pillar porcelain insulators, circuit breakers, transformers, bushings, etc. The quantity, location and shape of this product can also be determined to obtain the best effect according to the level, nature, and operating conditions of the on-site contamination.
    4. A well-installed silicone rubber booster shed can form a unified whole with the insulator.
    5. It has reasonable structure design and beautiful appearance. On-site application and installation are simple, timesaving and labor-saving.
    6. After installed our booster shed to ordinary porcelain insulators, it can improve the anti-pollution flashover effect of porcelain insulators and save money.
    7. After installed our booster shed to the power equipment, daily cleaning and maintenance can be reduced, saving time and effort.

    4. Our silicone rubber insulation coating protects power system from breakdown like bombing.
    5. Applied to equipment or elements need insulating handling, heat-conduction, flame resistant and moisture-proof protection like bare wire, naked bus, electric cable, wall crossing pipeline in high-low pressure substation and distribution system, HP motor, dry reactor, dry transformer and switch cabinet.
    6. Especially suitable for electric equipment working in dirt and humid environment.
    7. Excellent insulating property: Breakdown field strength of coating is over 20kv/mm.
    8. Can effectively stop general short trouble caused by small animal in transformer substation and person injury accident because of nude electric.
    9. Non-flammable, self-extinguishing, nice flame retardant with FV-0 class.
    10. Excellent heat-conducting: Heat conductivity 0.202W/ (m. K) 10 times of air, so it can release equipment's heat in time to prevent excess temperature.
    11. High strength, strong adhesion and high corrosion tolerate.
    12. Ozone, UV and environment aging-resistant.
    13. Not be easy break down by ozone and UV radiation.
    14. Service Life is at least 20 years in nature environment.

    Features of High Voltage Booster Shed

    1. Shed booster can be used on 10kV~1000kV switchgear, disconnector, post insulator, surge arrester and transformer insulation for increasing leakage path and enhancing pollution resistance.
    2. The silicon rubber shed booster can be widely applied on any station porcelain insulation.
    3. The shed number, shape and location shall determine in consideration with site pollution severity for optimized effect.
    4. They can be adhered on large surface to increase adhesion reliability.

    Apart from increasing the flashover performance of insulators, silicone rubber shield for porcelain insulators is perfect for reducing the surface electrical stress and leakage current and increasing the electric strength of the insulators.
  • Why It Is Necessary to Have Silicone Rubber Anti-pollution Flashover Booster Shed for Power System

    Due to the current changes in the global environment, the aggravation of fog and haze weather, the air quality is getting worse and worse, and the pollution flashover phenomenon has become more and more serious with the increase of operating time of the power system, which has brought direct and indirect economic losses to all countries. The artificial pollution test proves that the artificial pollution flashover voltage of the pillar insulator with the silicone rubber anti-pollution booster shed is more than double that of the pillar insulator without the booster shed. The silicone rubber anti-pollution booster shed can also be used to solve the problem of intensive the rain flash problem of the type of porcelain bushing. The silicone rubber anti-pollution booster shed has been widely used for more than ten years and tens of thousands of pieces and has achieved obvious anti-pollution flashover effects in practice. For the safe operation of the power system, escort!

Item Silicone Rubber Insulation Coating Heat Shrink Tube
Electrical Insulation Excellent electrical insulation. Breakdown Voltage is more than 25 kV/mm. Common performance.
Cover Effect Excellent adhesion.
The coating layer is intense, it could strongly stick to the equipment surface and could well resist to the corrosion caused by acid, alkali, salt and air.
Common cover effect especially in the connection part.
Thermal Conductivity The coating has closely attached to the conductor and has good thermal conductivity could better release the heat of equipment. Its thermal conductivity is 0.2W/ (m. k), which is ten times then air. Relatively poor due to there is air gap between the tube and equipment.
Flame Retardant Hard to burn and has good fire retarding ability up to FV-0 Class. Easy to deform, crack and broke.
Application Favorable hardness makes its construction time is short. (less than one working day)
It can well fit and protect the surface of special shaped equipment or components and special connection position so that to make the conductors as one.
Long construction time and need to disassemble the equipment.
It’s easy to crack and broken for the coating on the special shaped equipment or components and the connection or twist place.
Maintenance Easy to maintain and repair. The coating will not affect the dismounting of screw or bolt. Moreover, if recoating, the new coating can have integrated fuse with the old coating tightly. Although it’s also convenient to maintain and repair, but the connection place is easy to peel and broke.
Ageing Resistance Good hydrophobicity and resistance to ageing, dampness, ozone, radiation, UV, etc. make it free of maintenance and can serve for a long time. Its service life could be more than 20 years. Poor ageing resistance, its service time is about 5 years or even less especially in some bad environment the cracking and break phenomenon will happen.
Economic Excellent performance at reasonable cost. Lower cost.
