Stay insulators are low voltage insulators designed to fasten and counterweight dead-end poles by connecting with stay wires or guy grips. They prevent electric conduction accidents on stay wires, ensuring stability and safety. Typically used on 11kV and 33kV overhead line networks, L&R stay insulators are made of glazed porcelain per BS137 standards, suitable for outdoor operation.


1. Safety: Prevents accidental electric conduction on stay wires, enhancing safety. By isolating the stay wire from the pole, the insulator ensures that the stay wire does not become a path for electrical current, thereby reducing the risk of electrical accidents and improving overall safety for maintenance personnel and the public.
Stay insulators, used on stay wires, ensure wires don’t touch the ground if they break.
These insulators are crucial when poles fall or stay wires snap due to excess mechanical load, making them essential for overhead transmission lines.
Typically installed in the middle of stay wires, they prevent voltage in the lower portion of conductors if poles break. Their reliable performance ensures the safety and stability of power systems.

These insulators are crucial when poles fall or stay wires snap due to excess mechanical load, making them essential for overhead transmission lines.
Typically installed in the middle of stay wires, they prevent voltage in the lower portion of conductors if poles break. Their reliable performance ensures the safety and stability of power systems.
A typical stay insulator features two holes on opposite sides. Stay wires enter through one hole and exit through the other, with guy wires providing a secure connection. In the event of a pole or tower collapse, the stay insulator ensures that the wires remain insulated, preventing any voltage from reaching the ground. This design is crucial for maintaining safety and preventing electrical hazards in power systems.
The cost of stay insulators depends on several factors, including their physical, mechanical, and electrical properties. The voltage rating of the insulator also plays a crucial role in determining its price. For accurate pricing information, it is recommended to contact us—— a reputable stay insulator manufacturer
