Composite tension insulators are essential components used in electrical power transmission systems. They are designed to provide reliable support for power lines while also insulating them from the surrounding environment. The 66kV composite tension insulator is a high-quality product that can withstand high voltage and harsh environmental conditions.
This insulator is made from a composite material that is lightweight and resistant to environmental degradation, such as UV radiation and corrosion. Its unique design ensures it can handle heavy loads and extreme weather conditions without compromising performance.
The 66kV composite tension insulator is easy to install and maintain. Its simple design allows for quick and easy attachment to power lines, reducing installation time and costs. Maintenance is also minimal, as the insulator requires no special cleaning or upkeep beyond regular inspections.

1. The silicone rubber housing of Composite Line Post Insulator were taken shape by whole injection. It has good hydrophobicity, hydrophobicity migration and soil resistance, as well as excellent electrical insulation properties and aging resistance, which could prevent effectively those accidents of pollution flashover so as to ensure the safe running of high voltage transmission lines.
2. The modified ECR fiberglass reinforced epoxy resin rod is used as it has good resistance to high temperature, stess corrosion & acid attack, as well as fine damping action, high tensile strength (> 1200Mpa) and resistance to creep and fatigue failure, which effectively ensure the internal insulation quality and mechanical stength of insulators.

Compared with similar ceramic and glass insulators, silicone rubber insulators have the following advantages:
(1) Small size, light weight (1/7~1/10 times that of ceramic insulators with the same voltage), good elasticity of the shed, not easy to break, convenient transportation and installation, and economical.
(2) High mechanical strength. FRP rods have high tensile strength, which is 5-10 times that of ceramic materials. The cross-section of the core material is small, the product is small in size, light in weight, and high in tensile strength. It is easy to manufacture large-tonnage insulators above 300KN.
(3) High antifouling performance and good aging resistance. The silicone rubber injection molded shed has good hydrophobicity and mobility, which makes the insulator have high anti-pollution flashover voltage and good electrical corrosion resistance.
(4) Easy installation and maintenance, which can greatly reduce maintenance costs caused by power outages and manual labor intensity.
(5) The production process is simple and the delivery time is short.
We have been participating in various exhibitions at home and abroad from 2010 to 2020. At the exhibition, relevant people from the industry and us saw our products directly and closely.
1. All composite insulators are packed in plywood case, solid wood case or carton box etc for the better protectation on the products during land, air, and sea transportation. Several different grades of packaging can be offered depending on the mode of transport and the expected storage conditions. The packaging options that we offer are
1) standard grade/prefabricated packing,
2) economical grade/cardboard carton, and
3) best grade/closed plywood or wooden crate.
Since the user best knows their crate requirements, they should select the option that is most suited to their needs and include that information in the purchasing specification. Special packaging arrangements can be accommodated upon request.
2. Each container is marked with the number of insulators it contains, the catalog number, the manufacturer's name, and any other customer requests.
3. Each packing (wooden Cases or Paper ubes) attached specification and certification of products.
