Post Insulator Brackets are specialized hardware designed to mount and secure post-type insulators to power transmission and distribution poles. These brackets serve as mounting fixtures for post insulators ranging from 15kV to 34.5kV and can be installed on wood, concrete, сталь, or composite poles. The structure consists of a pole-shaped back and mounting points, available in various types including curved base brackets, side-mounted brackets, and uni-brackets.
Post Insulator Brackets enable versatile installation configurations, allowing insulators to be mounted either in phase-over-phase arrangements or on opposite sides of the pole for armless construction. When paired with post insulators, these brackets provide essential support for power line components while maintaining proper electrical isolation. The brackets are typically constructed from ductile iron or steel with galvanized coating to ensure durability and longevity.

Часто задаваемые вопросы (Часто задаваемые вопросы)
What are post insulator brackets used for?
Post insulator brackets are designed to mount and secure post-type insulators to power transmission and distribution poles. They can be used with wood, concrete, сталь, or composite poles, supporting insulators ranging from 15kV to 34.5kV systems.
What materials are post insulator brackets made from?
Post insulator brackets are primarily manufactured from ductile iron and galvanized steel. They undergo hot-dip galvanization according to ASTM A153 specifications to ensure corrosion resistance and durability.
How are post insulator brackets installed?
The brackets feature a pole-shaped back for convenient installation. They can be mounted in phase-over-phase arrangements or on opposite sides of the pole for armless construction, typically using 5/8-inch diameter bolts.
What voltage ratings do post insulator brackets support?
Post insulator brackets are designed to support insulators rated from 15kV to 34.5kV. The specific voltage rating depends on the insulator type and application requirements in the power distribution system.
What is the minimum order quantity (MOQ) for post insulator brackets?
There is typically no MOQ limit for first orders. For subsequent orders, a standard MOQ of 100 pieces is common, though this can vary by manufacturer.
Can custom sizes be ordered for post insulator brackets?
Да, custom sizes are available upon request. Manufacturers can produce brackets according to specific requirements while maintaining compliance with industry standards and specifications.
What mounting configurations are possible with post insulator brackets?
Brackets can be installed in horizontal positions, phase-over-phase arrangements, or on opposite sides of poles for armless construction. They provide flexibility in mounting options based on system requirements.
