When creepage has to rise but the tower window is fixed, alternating large and small sheds add leakage path within the same unit spacing.
What You Get With This Unit
Material
Toughened glass shell with hot-dip galvanised cap and pin, cemented and cured.

U70BLD Questions
Straight answers to the questions buyers ask before a first order.
What is the mechanical failing load of U70BLD?
The specified mechanical failing load is 70 kN. Every unit takes a routine tensile load test before it leaves the plant.
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.
What happens if a glass shell is damaged in service?
A toughened glass shell shatters and leaves the cap and pin carrying the line, so a zero-value unit can be spotted on a ground or helicopter patrol instead of a hot-line test.
