11kv Substation Post Insulator Composite Polymer Post Insulator For Transmission Line
11kv composite polymer post insulator for transmission line
Composite polymer insulator is composed of epoxy glass fiber core rod, silicon rubber shed and metal parts.
Composite polymer insulator is of high strength and light weight. A synthetic insulator is 1/5 of that of porcelain insulator, but the circum-tensile strength of insulator is very high. Generally, it can be above 6000mpa.
Its umbrella skirt is an organic polymer structure of silicone rubber.Therefore, it has a strong anti-pollution performance.
The product has reliable structure and will not damage the core rod. It belongs to the rod-shaped insulation structure.

① Light weight:
It's small in size and in light weight, it is about 1/5 to 1/9 of the porcelain insulator in the same grade voltage, so it' sconvenient for transportation and installation.
② Good anti-pollution
Composite insulator has a good anti-pollution performance, so it can operate safely in polluted areas, it requires neither annual cheaning nor maintaining at zero.
③ High antifouling property
Good aging resistance performance, strong ability of anti-pollution flashover and good electric corrosion resistance, can ensure that the internal insulation core will not be affected by moisture.
4. Strong shock resistance
Composite insulators have good brittleness resistance, strong shock resistance and there's no brittle fracture accident. Composite insulators are interchangeable with ceramic insulators.
The composite insulator has high mechanical strength, reliable structure and stable performance, which provides a guarantee for the safe operation of the line.
suitable for multiple industries, widely used in power grid, petro chemical, wind power, machinery, construction, communications and other industries.

3. After-Sale Service
Technical support on pre-sales stage. DINGLI has own survey and engineering company with more than 100 engineers. We have special pre-sales engineer to work with customer at early stage of the project.
Site assistance in Latin American market, so far we have sales and service center in Spain, Chile, Bolivia, Peru, Ecuador, Senegal, which will make a fast response for customer.
Warehouse and Emergency Supply
Warehouse and emergency supply for spare parts, damage parts and missing parts: DINGLI has built production line in Quito and warehouse for transmission line and distribution network in Ecuador, Bolivia and Senegal with common use spare parts.
Design and Consultant
Supported by both domestic engineering company and Quito tower design center, could provide technical consultant and design service within our scope of work. For Quito tower design center, most of the engineers are local staffs. The Design is based on ASTM protocols meantime with GB material standard, which will reduce the weight, and avoid the replacement on the profiles to save the working time.
