Name: China Customized Composite Line Post Insulator Manufacturers Suppliers Factory - Jasco Electric
Brand: Jasco
SKU: 319628927

Product Description

The composite line post insulator is a new type designed specifically for medium-voltage transmission and distribution lines as well as small substation equipment; it is widely used in power grid construction, upgrades, and various distribution projects.

The composite line post insulator primary load-bearing component is a high-strength fiberglass core rod capable of withstanding vertical loads, lateral wind pressure, and transient loads, offering exceptional mechanical strength and durability. The external insulating sheath, which serves as a protective layer, is manufactured via integral injection molding using heat-resistant silicone rubber; it exhibits excellent water and aging resistance, making it suitable for harsh environments, such as windy and sandy coastal areas.

Metal components - including the galvanized steel base and the conductive rod welded to the top - offer superior corrosion resistance, ensuring the product's durability and long service life. Suitable for both straight and angled line sections, the standardized design accommodates cross-arms of various cross-sectional shapes, thereby simplifying installation and reducing maintenance costs.

The composite line post insulator Compared to traditional porcelain insulators, this product is lighter, corrosion-resistant, and poses a lower fire risk, while also delivering a high safety factor and stable insulation performance.

The composite line post insulator provides a safe, reliable, and cost-effective insulation and support solution for medium-voltage power lines.

Our Product Advantage

1. Direct Sales Model

As a professional manufacturer of power equipment components, we control the entire production process - from core rods and silicone rubber housings to metal end fittings. Every product undergoes rigorous inspection before leaving the factory.

2. Weather-Resistant Design

Engineered for long-term durability, the product resists cracking in harsh environments, including deserts, coastal areas (salt spray), and regions with extreme humidity. The fiberglass core rod utilizes a high-strength, low-water-absorption epoxy resin matrix, eliminating the risk of dielectric breakdown. The connection between the steel end fitting and the core rod features a dual-protection system - combining patented casting technology with high-performance sealant - to effectively prevent water ingress and corrosion.

3. Superior Pollution Flashover Resistance

The design provides ample creepage distance and excellent insulation performance. Electrical and power-frequency impedance values exceed standard requirements, effectively reducing the risk of flashover in heavily polluted areas and making it an ideal choice for overseas projects in hot, dusty climates.

4. Reliable Mechanical Performance

Available in various mechanical failing load ratings, including 4kN, 6kN, 8kN, and 10kN. The streamlined design and robust fastening system ensure exceptional bending and torsional strength. Materials are specifically selected to withstand mechanical stresses caused by strong winds and seismic vibrations, ensuring high operational reliability.

5. Reduced Project Costs

Compared to traditional porcelain insulators, this product is lighter, simplifying on-site lifting and installation; this shortens construction schedules and lowers labor costs. Additionally, the product offers low risk of spontaneous failure and requires minimal maintenance.

6. Comprehensive Specifications and Efficient Export Services

From 10kV to 220kV. Sample orders are supported, with a standard lead time of approximately 20 days. In addition to providing various certifications (such as EC and ISO), we accommodate requests for both standard and customized packaging.
