Insulators are devices installed between conductors of different potentials or between conductors and grounding components, capable of withstanding voltage and mechanical stress.
Insulators are a special type of insulation control that can play an important role in overhead transmission lines.
In power systems, insulators are crucial components that ensure the safety and stability of power transmission. As an experienced insulator manufacturer and supplier, Electric Powertek Company Ltd. focuses on providing high-quality glass insulators, porcelain insulators, and composite insulators to customers worldwide, catering to different voltage levels and application scenarios.
✔️ Source Factory | 30 years of insulator R&D and manufacturing experience, monthly production capacity of 2 million pieces

Features: Made from high-strength tempered glass, glass insulators are lightweight, compact, have high mechanical strength, and are easy to inspect after self-explosion. The surface coating material has excellent hydrophobic properties, effectively resisting pollution and reducing surface leakage current, achieving maintenance-free operation.
Applications: Widely used in high-voltage transmission lines, especially suitable for highly polluted and humid environments.
Features: Porcelain insulators offer excellent insulation performance, aging resistance, and self-cleaning capabilities. Their robust structure ensures long-term stable operation in harsh environments.
Applications: Suitable for medium and low voltage transmission lines and substation equipment, a classic choice in traditional power systems.
Features: Composite insulators are made with a fiberglass-reinforced epoxy resin core rod and silicone rubber housing, offering advantages such as being lightweight, easy installation, and excellent anti-pollution flashover performance. Their unique structural design makes them perform exceptionally well in highly polluted and high-altitude areas.
Applications: Suitable for high voltage and extra-high voltage transmission lines, as well as special scenarios requiring extremely high insulation performance.
