There are types of spool insulator 53 Series, ED Series and 1617. We can also produce the spool insulator according to the customer requirement.


Porcelain spool insulators, also known as shackle insulators, are used primarily in low voltage power lines to provide insulation and support for conductors. They are often installed on building racks where wires enter structures, and they can also be used for wire transposition, allowing wires to cross each other. These insulators are made from high-quality porcelain that is vitrified and glazed to ensure durability and resistance to environmental factors.
Their applications include use in distribution systems, overhead lines, and as part of electrical fittings to simplify the structure of electrical systems. They are customizable in size and color, making them versatile for various electrical transmission needs.


Shackle insulators.
The spool insulator is a type of insulator that provides insulation on both the primary and secondary conductors of a distribution line.
A typical spool insulator has a hole at the center which provides a platform for mounting. The groove at the outside making it easy for you to mount the wire.
A spool insulator is mainly used to insulate and support the secondary conductors at the pole.
A spool insulator is mounted to the pole using various clevis configurations and is compatible with all manufacturer’s hardware designs.
A spool insulator made of ceramic and porcelain is customizable, so that the sizes, colors, and other specifications can be designed to compatible with the conductors of an electric transmission line.
The price of a spool insulator is not uniform across the board. There are various factors that determine the actual price of the insulators.
1.The material of the insulator.
2.The specification you required
3.The manufacturers and suppliers you choose.
