FAQ
Q: What is the difference between line post insulators and station post insulators?
A: Line Post Insulators are installed directly on overhead power distribution/transmission line poles or crossarms to support bare conductors. They are optimized for high wind loads, vertical mechanical forces, and outdoor weathering.
Station Post Insulators are designed for high-voltage substations and power plants to support rigid busbars, disconnect switches, and switchgear apparatus, emphasizing high cantilever stiffness and torsion resistance.
Q: How do I select the right creepage distance for my project?
A:The creepage distance depends on the system voltage (kV) and the environmental pollution level defined by IEC 60815:
Light / Medium Pollution (Inland/Rural): 16 – 20 mm/kV
Heavy Pollution (Industrial/Urban): 25 mm/kV
Very Heavy Pollution (Coastal/Desert/Salt Spray): 31 mm/kV or higher
