Product Overview

A Chinese National Standard GB BLQ-10/315 transformer bushing rated 10 kV, 240 mm tall and 115 mm in diameter. Creepage is 180 mm with a 165 mm arcing distance, and the bushing weighs 1.7 kg. It is the high voltage member of the GB bushing pair, matched to the GB B-1/315 on the low voltage side of the same transformer.

Why Buyers Choose This Part

• GB National Standard pattern matched to the B-1/315 LV bushing
• 180 mm creepage against a 165 mm arcing distance at 10 kV
• 1.7 kg unit weight for a 10 kV class bushing
• 240 mm height suits compact transformer covers

Where It Is Used

• High voltage side of GB standard distribution transformers at 10 kV
• Projects specified against Chinese National Standard
• Transformer builds pairing GB HV and LV bushings
• Replacement of installed BLQ-10/315 bushings

Who It Suits

• Transformer manufacturers building to GB standards
• Buyers on GB-specified export projects
• Distributors supplying GB pattern bushings

What Goes Wrong Without The Right Part

• GB pattern HV parts not carried by DIN and EN focused suppliers
• Mismatched HV and LV bushing standards on one transformer
• Height clearance limits on compact transformer covers
• Creepage figures that do not match the GB drawing

How It Is Built

• Chinese National Standard GB BLQ-10/315
• Rated voltage 10 kV
• 240 mm height
• 115 mm diameter
• 180 mm creepage distance
• 165 mm arcing distance
• 1.7 kg weight

How It Compares

GB B-1/315	The B-1/315 is the 1 kV LV part at 105 mm high with 85 mm creepage and 0.29 kg. The two are normally ordered together for one transformer.
DIN 10NF250A	A comparable 10 kV class bushing on the DIN pattern with a C110 alumina body and choice of glaze colour. Order by the standard on your drawing.

Before You Order And After It Arrives

• Order the matching B-1/315 for the LV side of the same transformer
• Check the 115 mm diameter against the terminal board opening
• Allow for the 240 mm height above the cover
• Keep the creepage surface clean in outdoor service
