Silicone rubber Long Rod Insulator, also known as composite Insulators or polymer insulation, is used in high voltage transmission lines and distribution lines.
It is particularly useful in areas with high levels of pollution, as it has a large span, compact design, and a high mechanical tensile load.Transmission lines are supported on steel towers by long rod insulators, which isolate the lines from the tower.
They are essential to the reliable flow of power. Long rod insulators are often used in multiple-insulator combinations, depending on the transmission voltage and usage environment.
Composite long rod insulators are typically utilised in tension strings in anchor towers and dead-end towers as well as suspension strings in straight-line supports. Additionally, they are utilised in the gateways or jumps of outside substations.
Over traditional ceramic insulators, the usage of polymeric/silicone rubber base insulators has a number of advantages, including light weight, unbreakability, hydrophobicity, resistance to ozone & UV radiations, resistance to earthquake shocks, self-cleaning qualities, and vandalism resistance.
There are at least two insulating components in a composite insulator, polymer insulator, or silicon rubber insulator, such as a fibreglass core and a housing with metal end fittings. It offers various advantages over porcelain or glass insulators and is a growing trend.
The Global long rod insulator silicone rubber market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Long rod polymer insulators are produced by one of the top insulator manufacturers, Xiangyang Guowang Composite Insulators Co., Ltd. Composite insulators are similar to established insulators in terms of composition and characteristics.
the primary component of the insulation’s cover, core, and fins. polymer silicone rubber Silicon Rubber prior to the addition of additives.
The amount of carbon in the final product will not exceed its weight. The long rod polymer insulators are typically constructed utilising corona rings, ECR fibreglass rod, metal end fittings, and polymer housing.
The sheath is made of silicone rubber of the HTV type, which shields the core from UV rays and outside attacks and ensures water tightness and good performance in polluted surroundings.
The rubber that will be utilised is entirely devoid of EPDM ethylene-propylene-diene monomer. The silicone rubber needs to be shielded from heat generated by partial discharges.
