Basic Info.
Product Description
Product introduction:
Low voltage pure-porcelain bushing with flange structure plays an important role in reducing the level of partial
discharge,improving the flexural strength and reducing leakage.
In addition ,the cast aluminum flange,instead of the previous traditional pressure claw structure,not only
improves the overall appearance of the product,but also facilitate the on-site installation.
Presently,the annual production capacity of 24kv and above voltage bushing is 30,000 and nearly 5000
supporting equipment for 110kv and above voltage current transformer is provided annually. We are capable of
high and efficient productivity in casting,processing,assembling and testing. The earliest product has been
running for more than 10years.
With continuous innovation and improvement,our products will become perfet and we will keep rolling out new
products eliminating hidden dangers in sealing bushings and achieving flexural strength and excellent
appearance.
