What This Type Is For
40kN standard disc suspension glass insulator CTV254 is a very common and popular glass insulator in Chinese market and overseas market such as Vietnam, Iran, Algeria etc. Jiangxi huayao electric Co.,ltd is professional in produce this item, the daily output of this item is 10000 pieces.
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
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.

U40B Questions
Straight answers to the questions buyers ask before a first order.
What is the mechanical failing load of U40B?
The specified mechanical failing load is 40 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.
