A product profile of the high voltage composite insulator
and composite insulator (
Other names: composite insulator)
: insulation by glass fiber resin core rod, synthetic materials sheath, umbrella skirt, and ends with the connection of insulator.

Ceramic insulator is * appearance of insulator, the craft is simple, but is not the advantage of not easy to accumulate dirt, actually at the scene the filth of the porcelain insulator is also very serious.
Glass insulator relative ceramic insulator * big advantage is no need to inspect for zero, zero glass insulator will self destruct.
Composite insulator is more later in the development of insulator, advantages of light weight, great strength, breakdown, not * important advantage is the ability to resist pollution flashover.
But, after all, is a composite material, in contrast to the inorganic composition of glass, porcelain, the phenomenon of aging is more outstanding.
A product profile of the high voltage composite insulator and hv insulator products made of glass fiber epoxy resin lead pull rod (
, silicon rubber umbrella skirt (
, hardware (
Of three parts.
The silicon rubber umbrella skirt with the injection molding process, so as to solve the key problems affect the reliability of the composite insulator interface electrical breakdown.
Glass pull rods and hardware connection using * better crimping process, equipped with automatic flaw detection system, the acoustic intensity is high, beautiful shape, small volume, light weight, hardware can prevent rust, galvanized are interchangeable with porcelain insulator is used, the product structure, reliable and don't damage the mandrel, can give full play to its mechanical strength.
Superior electrical properties, high mechanical strength, internal guide bearing epoxy glass pull rod tensile bending strength 2 times higher than ordinary steel, 8 ~ 10 times that of high strength ceramic materials, effectively improve the reliability of safe operation.
Fouling resistance performance is good, good anti-pollution performance, anti pollution flashover strength is strong, the wet resistance voltage and pollution withstand voltage for the same creepage distance of the porcelain insulator 2 ~ 2.
And don't need to clean, can composite insulator in the safe operation of the heavy polluted areas.
Small volume, light weight,
Only for porcelain insulator with voltage grade 1/6 ~ 1/9)
Lightly and ingeniously structured, easy to transport and install.
Has good hydrophobic properties of silicon rubber umbrella skirt, its whole structure ensures that the insulation is not be affected with damp be affected with damp, do not need preventive insulation monitoring test, without cleaning, reducing the workload of daily maintenance.
Good seal performance, electric erosion resistant capability is strong, the umbrella skirt TMA4 material resistant to tracking.
Level 5 levels, good ageing resistance, corrosion resistance, low temperature resistance, can be applied to -
Has a strong impact resistance and vibration resistance, its good prevent brittleness and creep resistance, not easy broken, high resistance to bending and torsional strength, can withstand the internal pressure, explosion-proof power, are interchangeable with porcelain and glass insulator.
Composite insulator series products, its mechanical properties and electrical properties are better than that of porcelain insulator, running safety margin is large, is for the use of electric power line to update products.
Composite insulator classification: composite suspension insulator, composite insulator needle, composite pillar (
Insulator, electrification railway insulator, falling type fuse, hollow composite insulator.
