Product Description

Glass insulator is a device used to support and insulate electrical wires. It is made from toughened glass, which enhances its strength and durability. 

Currently, toughened glass insulators are among the most widely used insulators in power lines due to their excellent electrical insulation properties and mechanical strength.

INSULATORS COMPONENTS

Cap and pin type of suspension glass insulator consists of the following elements: insulating part (or dielectric), pin, cap and locking device.

A locking device is a part of insulator for fixation and is manufactured of stainless steel. The assembling of an insulator is performed by cement-send mix followed by thermal wet treatment. The assembling may be performed with Portland cement or aluminosilicate cement.

A cap is for movable fixation of an insulator to another one or fittings. Caps are produced by casting from high-strength cast iron or malleable cast iron.They are made in the method of hot-dip galvanizing method to ensure its corrosion-resistant property.

Caps for DC insulators are equipped with a collar made by casting.

The insulating part is manufactured by the compaction method from low-alkali glass followed by toughening. 

FEATURES OF GLASS INSULATOR

Glass insulators are a crucial component in the insulation and support of overhead transmission lines. In the early years, insulators were primarily used on power poles. However, their usages evolve to include high-voltage power line connection towers, where multiple disc-shaped insulators are hung at one end to increase the creepage distance. These insulators are commonly made of glass and are vital for maintaining insulation in power transmission systems.

TECHNICAL PARAMETER

ADVANTAGES OF GLASS INSULATOR

• Raw Material:
  

Made of tempered(toughened)glass, which is more stable compared to materials used for porcelain insulators.

Suitable for various weather conditions; waterproof and moisture-proof.

Able to function normally in rainy or humid environments.

• Appearance:

Glass transparency makes it easier to detect small cracks, internal defects, or damages during visual inspections.

• Performance:

Excellent insulation performance and reliable operation.

High hardness, resistance to bending, and effective anti-fouling properties.

The company is the world’s best Composite Insulator supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

Strong mechanical and electrical performance, small size, lightweight, and long service life.

• Mechanical Strength:

High mechanical strength, especially on the surface, which is resistant to cracks and slow aging.

• Ease of Testing:

Preventive testing can be minimized since any damage to the glass is easily detectable during line inspections, allowing operators to identify problems visually.

• Self-Cleaning Properties:

Glass insulators have smooth surfaces, which reduce the accumulation of dirt, dust, and pollutants, especially in outdoor environments. Rainwater naturally helps clean the surface, maintaining performance.

• Resistant to Weathering:

Glass insulators have excellent resistance to UV radiation and other environmental factors, maintaining their strength and transparency over time without degradation.

• Thermal Stability:

Glass has good thermal properties, meaning it can withstand extreme temperature variations without cracking or losing insulation properties.

• Resistance to Corrosion:

Glass is highly resistant to corrosion, especially in harsh industrial or coastal environments, unlike metal components that can degrade due to chemical exposure.

• Safety Factor:

In case of damage, glass insulators tend to shatter into small, blunt pieces rather than large, sharp shards. This makes them safer to handle and reduces the risk of injury during maintenance or replacement.

• Environmental Friendliness:

Glass is a recyclable material, and glass insulators have a lower environmental impact in terms of disposal compared to other materials like plastics or certain ceramics.

• Long-Term Cost Efficiency:

Due to their long service life and reduced need for regular preventive testing or cleaning, glass insulators can offer lower maintenance costs over time compared to other insulator types.
