Structure and Materials

Structure Details
Material Characteristics

Utilizes high-strength tempered glass with improved mechanical properties and thermal shock resistance. Smooth surface with hydrophobic properties prevents dirt adhesion.

Zero-value self-explosion: Faulty units automatically burst for easy visual identification.

Metal Accessories

Cap & Foot: Hot-dip galvanized steel or aluminum for superior corrosion resistance, bonded with high-grade cement adhesive.

Locking Pin: Available in W-pin or R-pin designs (W-pin standard for U160BLP).

Advanced Design

Anti-fouling umbrella skirt with large creepage distance (≥ 450mm) suppresses arc and pollution flashover. Optimized shape prevents continuous rainwater lines.

Frequently Asked Questions

What is the primary application of the U160BLP insulator?
It is designed for high-voltage and ultra-high voltage transmission lines (110kV to 500kV), particularly in environments with high pollution, humidity, or salt fog.
What does the "P" stand for in the model code?
The "P" indicates that it is an Anti-Pollution type, featuring a specialized umbrella skirt design to handle industrial dust and harsh environments.
What is the "Zero-value self-explosion" characteristic?
This is a safety feature where the glass disc will burst if the insulator loses its insulation capability, allowing maintenance teams to easily spot faulty units from the ground.
Which standards does this product comply with?
It complies with major international and national standards including GB/T 7253, JB/T9683, and IEC60305.
What materials are used for the metal components?
The caps and feet are made from hot-dip galvanized steel or aluminum to ensure long-term corrosion resistance in outdoor settings.
Can the locking pin type be customized?
Yes, depending on requirements, the insulator can be supplied with either a W-pin or an R-pin, though the W-pin is standard for the U160BLP model.
