Stay Insulator – Important for Electrical Safety and Structural Stability
A stay insulator or guy strain insulator are used for electrical isolation of the low part of the stay wire from the energized upper portion. The insulator is a key component of overhead transmission and distribution lines. Purpose of the stay insulator is to prevent electrical leakage from the energized electrical wire; which could injure people and conduct to earth.
Why Stay Insulators are Important
Stay insulators are important for both electrical safety and providing mechanical stability to support structures.If insulation fails, because of wet and dry arcing or other forms of leakage.
Key attributes
High dielectric strength
Long–lasting, UV, and impact resistant
Available in porcelain
Deflection rated to support high mechanical stress
Commonly used in
Power distribution systems, including overwire to classified wire.
Railway systems.
Telecommunication lines.
Wooden and metal electrical utility poles.
Energy distribution for rural electrification.
Advantages of insulators
Increased safety in power systems / lines / wiring by electrically isolating stays from active wires.
Stay provide an incredibly long-lasting product with zero maintenance.
Stay are not notable in their susceptibility to change in temperature extremes, or to UV.
Stay assist in maintaining regulatory compliance for electrical‘autant that become direct path to energy.
