Product Description
Overview
Low-voltage overhead power line insulators are used exclusively in AC or DC power lines with operating voltages of 1,000 volts or less to provide insulation and secure the conductors. They include: low-voltage pin-type insulators (referred to as pin insulators); low-voltage disc‑type insulators (referred to as disc insulators); and low-voltage rod‑type insulators (referred to as rod insulators).
Structure and Model Description
1. Low-voltage line pin-type insulators are assembled from porcelain components and iron feet. The top of the porcelain body features a wire groove, which bears the conductor load, while the lower portion is equipped with shed skirts that provide a long creepage distance and offer a certain level of electrical insulation performance. The newly redesigned standard product is smaller in size and lighter in weight than the previous model, with improved self‑cleaning properties, while its electromechanical performance remains at the same level as that of the earlier 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 offers butterfly insulators in a three-shed configuration for export.
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 the number 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.
