Glass Standard Profile Suspension Insulators LXWP7-160 / U160BSP/146
High Voltage Disc Type Suspension Insulators Tempered Glass Insulator U160BSP
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 160 kN, routine tested at 80 kN.
Creepage per unit
550 mm of leakage path in a single unit, so string creepage can be budgeted without guesswork.
Coupling
20 mm ball and socket coupling to match existing line hardware.
Shipping weight
8.80 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.

U160BSP/146 Questions
Straight answers to the questions buyers ask before a first order.
What is the mechanical failing load of U160BSP/146?
The specified mechanical failing load is 160 kN, and the routine test load is 80 kN.
How much creepage distance does this unit give me?
One unit gives 550 mm of creepage distance at 146 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 20 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.
