Specifications
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.

Product Advantages
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.
2. Stability: Secures and counterweights dead-end poles, preventing collapse. The stay insulator provides crucial mechanical support to the poles, especially at the ends of the line, where the tension is greatest. This helps in maintaining the structural integrity of the poles and prevents them from bending or collapsing under the load of the overhead conductors.
3. Versatility: Suitable for 11kV and 33kV overhead line networks. These insulators are designed to be used in various voltage levels, making them adaptable to different types of electrical distribution systems. Their versatility allows them to be effectively used in both medium and high-voltage applications.
4. Durability: Made of glazed porcelain according to BS137 standards, ideal for outdoor use. The use of high-quality glazed porcelain ensures that the insulators are resistant to weathering, pollution, and mechanical wear. Compliance with BS137 standards guarantees their reliability and performance in harsh outdoor environments.
5. Flexible Connection: Features two holes for various installation methods. The design includes two holes that allow for flexible and secure attachment to the stay wire and pole. This versatility in connection options makes installation easier and more adaptable to different pole and stay wire configurations.
6, Customization: Can be designed and customized based on customer specifications and drawings. Manufacturers can tailor the design and dimensions of the insulators to meet specific requirements and drawings provided by customers, ensuring that the product fits perfectly into their unique infrastructure needs and operational conditions.
Application Places
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.
