Overview
Low-voltage overhead power line insulators are used exclusively in AC or DC power lines with operating frequencies and voltages not exceeding 1,000 volts, serving to insulate and secure the conductors. They include: low-voltage pin-type insulators (referred to as pin insulators); low-voltage butterfly-type insulators (referred to as butterfly insulators); and low-voltage spool-type insulators (referred to as spool insulators).
Structure and Model Description
1. Low-voltage line pin-type insulators are assembled from porcelain components and iron feet. The porcelain body features a wire groove at its top, which bears the conductor load, and an umbrella skirt at its base, providing a long creepage distance and good electrical insulation performance. The newly redesigned standard model is smaller in size, lighter in weight, and exhibits superior self‑cleaning properties, while maintaining the same electromechanical performance as the previous version.
PD—low-voltage line pin-type insulator; the numbers 1, 2, and 3 following the dash indicate the product’s shape and size sequence, with No. 1 being the largest size; T, M, and W denote iron crossarm, wooden crossarm, and bent‑foot types, respectively.
2. Butterfly-type insulators feature two large shed skirts shaped like a butterfly; the conductor is tied between the two sheds, with a central hole for securing the connection to the crossarm via a pin. Our factory also supplies butterfly-type insulators in a three-shed configuration.
ED—low-voltage line butterfly-type insulators: the numbers 1, 2, 3, and 4 following the hyphen indicate the product’s shape and size sequence; for export products, the letters B and C appended to these numbers denote differences in shape and specifications.
3. Spool-type insulators have two or more ribs; the conductor is tied between the upper and lower sheds, with a central hole for securing the connection to the crossarm or cleat using a pin.
EX—low‑voltage line post insulators; the numbers 1, 2, 3, and 4 following the hyphen indicate the product’s shape and size sequence. All insulators comply with the national standard GB 1386‑78, “Insulators for Low‑Voltage Overhead Power Lines.” When placing an order, please specify the product name, model and code, glaze color, and quantity.Factory code Model number Drawing number H h D d1 d2 R D8805 EX-1 2 90 45 85 55 22 12 D8806 EX-2 2 75 37.5 70 45 20 10 D8807 EX-3 2 65 32.5 65 40 16 8 D8808 EX-4 2 50 25 55 35 16 6 Production Capacity
