Medium & High Voltage 27kV Composite Polymer Suspension Type Insulator

Insulators are widely used in overhead transmission lines to provide mechanical support and electrical protection, as well as in distribution lines and substations. Silicone rubber is the most widely used polymeric insulation material for high voltage insulators. Depending on voltage considerations, different kinds of insulators are used in power systems,we have Pin insulator,strain insulator,suspension insulator,post insulator,long rod insulator,horizontal post insulator,Railway insulator,shackle insulator,stay insulator.

1. Excellent Electrical Insulation Performance

Provides highly reliable insulation isolation, forming a high‑resistance barrier between live parts and grounded components. It effectively suppresses leakage current and short‑circuit risks, with dielectric properties fully meeting IEC 60383 and GB/T 775 standards, ensuring safe and stable operation of power systems.

2. Outstanding Mechanical Bearing Capacity

Capable of withstanding the full weight of overhead lines, along with strong external forces including wind loads, ice loads, and conductor tension. Its robust mechanical design maintains stable line geometry and prevents structural failure even under extreme weather and operating conditions.

3. Superior Environmental & Corrosion Resistance

Exhibits strong resistance to acid rain, salt spray, industrial dust, and chemical pollutants. It effectively avoids performance degradation, cracking, or aging caused by harsh environments, maintaining consistent insulation and mechanical properties throughout long‑term outdoor service.

1. Overhead Transmission & Distribution Lines

Widely used in overhead power lines for voltage levels from 0.4 kV to 500 kV. It supports and insulates conductors, bearing mechanical loads while isolating electricity, ensuring stable power transmission in urban, rural, and mountainous power grids.

2. High‑Voltage Substation Applications

Applied in indoor and outdoor substations as key insulation components for switchgears, transformers, and busbar connections. It provides reliable insulation and support under high‑voltage conditions, ensuring safe operation of substation equipment.

3. Industrial & Mining Power Systems

Suitable for power distribution in industrial plants, mines, petrochemical facilities, and other heavy‑duty environments. It resists chemical corrosion and pollution, maintaining stable insulation performance in harsh industrial working conditions.

Q: How do you ensure that the product quality meets the standards?

A: Each product export will go through Visual & Dimensional Inspection, Temperature Rise Test, Mechanical Operation Test, Sealing Test, Vibration Test, Shock Test and striker Test.

Q: Why should I choose your company?

A: Superior quality, low price, professional technical team, rich experience, timely delivery time, excellent after-sales service, and good reputation.

Q: How long will it take for me to receive the quotation?

A: For customized products, we will provide a quotation within 48 hours after you provide the required product details, as we need time to calculate costs, but we will provide a quotation as soon as possible.
