Electrical insulation performance grade: The product surface is coated with a dense anti-fouling glaze layer, which is not prone to accumulation of dirt and has excellent anti-chargation effect. It can maintain a stable insulation state in medium and low voltage electric fields, effectively reducing the risks of line flashover and leakage, and is suitable for complex outdoor electrical usage environments.
Robust mechanical structure: The glued zinc sleeve is tightly connected to the steel foot, capable of withstanding multiple mechanical stresses such as the weight of the conductor, outdoor wind load, and ice load. It is resistant to vibration and impact, has no risk of loosening or falling off, and has a long service life.
Standardized design with high adaptability: It fully complies with international and domestic industry standards. The structural dimensions are precisely matched with mainstream medium and low voltage line fittings and accessories. Installation does not require special tools. It can be directly replaced with products of the same specification and also supports custom glaze color.
