What This Type Is For
210kN double-umbrella disc suspension glass insulator UG210B170/450D 20R
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
Rated strength
Specified mechanical failing load of 210 kN, routine tested at 105 kN.
Creepage per unit
450 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
9.00 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.

UG210B170/450D 20R Questions
Straight answers to the questions buyers ask before a first order.
What is the mechanical failing load of UG210B170/450D 20R?
The specified mechanical failing load is 210 kN, and the routine test load is 105 kN.
How much creepage distance does this unit give me?
One unit gives 450 mm of creepage distance at 170 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.
