What This Type Is For
U40BP high-voltage toughened glass insulator is a core insulation product designed by Huayao Electric specifically for medium and high-voltage transmission lines as well as power distribution projects in heavily polluted areas.As a 40kN class anti-pollution insulator, it precisely meets the insulation and mechanical requirements of medium-voltage power distribution networks, making it a cost-effective choice to ensure the safe and stable operation of 10kV~35kV power lines under complex working conditions.
Coastal salt fog, cement dust and chemical fallout bridge a standard shed and cause flashover. A deeper fog profile buys creepage distance where washing is impractical.
What You Get With This Unit
Rated strength
Specified mechanical failing load of 40 kN, routine tested at 20 kN.
Creepage per unit
190 mm of leakage path in a single unit, so string creepage can be budgeted without guesswork.
Coupling
11 mm ball and socket coupling to match existing line hardware.
Shipping weight
2.5 kg net per unit, which sets crate weight and freight cost for the string.
Material
Toughened glass shell with hot-dip galvanised cap and pin, cemented and cured.
Traceability
Routine tensile load test on every piece, with the process record kept against the production batch.

U40BP Questions
Straight answers to the questions buyers ask before a first order.
What is the mechanical failing load of U40BP?
The specified mechanical failing load is 40 kN, and the routine test load is 20 kN.
How much creepage distance does this unit give me?
One unit gives 190 mm of creepage distance at 110 mm unit spacing. Multiply by the number of units in the string and compare the total against the mm per kV your pollution class requires.
Which coupling size does it use?
The ball and socket coupling is 11 mm. Confirm this against the fittings already specified for the project so the string assembles without adapters.
Which standards does this toughened glass insulator follow?
Designs follow GB, ANSI, BS, DIN, AS and IEC dimensions. Type test reports are available from Xi'an High Voltage Apparatus Research Institute Co., Ltd. and the National Ceramic Product Quality Inspection and Testing Center.
Can I have the goods inspected before shipment?
Yes. Buyers are welcome to inspect in person, and Huayao accepts third-party pre-shipment inspection appointed by the buyer, including Intertek, BV and SGS.
What is the production capacity behind this item?
The plant runs one natural-gas electric melting kiln with a melting area of about 50 m² and two production lines, with an annual capacity of six million pieces of AC and DC glass insulators. Stock is held on common types.
