Wide Voltage Range & Strong Compatibility：Standard porcelain disc structure, compatible with ball-and-socket and clevis-and-tongue connections for 6-33kV voltage classes. Directly matches conventional hardware of medium and high-voltage overhead power systems without extra modification, covering all mainstream construction demands.
Excellent Electromechanical Performance：Rigorously electromechanical tested with compliant strength and pressure resistance. Porcelain body and metal fittings are tightly cement-bonded, stably bearing loads with non-attenuating insulation in complex outdoor working conditions.
Mature Design & Broad Scene Adaptability：Classic disc insulation structure fits medium and high-voltage overhead power system suspension needs, perfectly matching universal industry towers and hardware, with easy installation and low later maintenance frequency.
