Composite Deadend Insulators: A Modern Solution for the North American and South American Compliant with ANSI C29.13: American National Standard for insulators-Composite Distribution Deadend Type
The evolution of overhead power transmission and distribution demands components that offer superior strength, durability, and reliability. Composite deadend insulators have emerged as the modern successor to traditional porcelain and glass, providing critical performance advantages, especially in the diverse and demanding climates of North and South America. Our product line, fully compliant with the ANSI C29.13 standard for composite insulators, is engineered to meet these rigorous demands.
Key Features and Compliance
Our DS Series of composite deadend insulators, including models DS15, DS28, DS35, DS46, and DS69, is designed for terminating transmission and distribution lines on utility poles or transmission towers. Adherence to the ANSI C29.13 standard guarantees consistent quality, safety, and performance, ensuring seamless integration into existing grid infrastructure across the North American and South American.
End fittings: clevis and tongue
Tensile Strength: 10000LB(44.5kN)
Designed for Reliability and Ease of Installation
The insulators are equipped with clevis and tongue end fittings. This standardized hardware configuration is widely preferred for its strength and ease of connection to pole or tower crossarms, allowing for efficient and secure installation.
The housing of each insulator features a straight shed design. This profile is highly effective in shedding water and contaminants, maintaining a high electrical performance in polluted coastal areas, industrial zones, and regions with heavy rain or frequent fog. The core of the composite insulator is a fiberglass-reinforced epoxy rod, which is not only exceptionally strong but also lightweight and immune to the thermal and mechanical shock that can damage brittle materials.
Primary Applications and Regional Focus
These composite deadend insulators are ideally suited for:
Termination Points: Used at the dead-ends of distribution and transmission lines on wooden poles, concrete poles, or lattice towers.
Corner Structures: Providing the mechanical strength to change the direction of power lines.
North American and South American Market: Specifically deployed to strengthen the electrical infrastructure throughout North and South America, where their pollution resistance, high strength-to-weight ratio, and longevity offer a significant operational advantage.
In summary, our ANSI C29.13-compliant DS Series composite deadend insulators deliver a reliable, standardized, and high-performance solution for utility applications, combining a 70kN tensile strength, practical clevis and tongue fittings, and a proven straight shed design for the dynamic power grids of the North American and South American.
