We ,Dalian Hivolt Power System Co., Ltd. have supplied high quality glass insulators for transmission lines up to 500kV for domestic National Power Grid and overseas market due to high quality and competive price . we exported to UK, South Africa , South America , Ireland etc. If you are interested in this type of Insuators , please feel free to contact with us .
Toughened Glass Insulators
Type : fog type & normal type
Class: up to 300 kN (E& M faliing load value)
Standard: we can supply those insulators in IEC, ANSI , AU standards.
we can design insulators according to customers requirements.
Below is some data for 240kN insulator for example:
Technical Specifications for U240BP toughened glass insulator :
| | Technical Specification | Unit | Value |
| 1 | Spacing | mm | 170 |
| 2 | Shed Diameter | mm | 330 |
| 3 | Creepage Distance | mm | 550 |
| 4 | Mechanical Failing load Strength | KN | 240 |
| 5 | Power Frequency Withstand Voltage | | |
| | dry | KV | 90 |
| | wet | KV | 55 |
| 6 | Lightning Impulse Flashover Voltage | KV | 140 |
| 7 | Puncture Voltage | KV | 130 |

HIVOLT toughened glass offers below features:
High residual strength and no risk of line drop: Glass insulators can only exist
in two well defined conditions: intact or shattered.There is no intermediate cracked or punctured
state. Therefore it is easy to quickly inspect strings , with no need for
additional test instruments, it will save more time and cost.
Safety in construction Because of the impossibility of inducing hidden internal
damage, it is not possible to install a faulty string of glass insulators. so it skips routine test before transmission line constructions.
Puncture resistance glass insulators resist the most extreme surges
such as switching surges, steep front lightning strikes and power arcs. There can be no hidden
puncture in a glass insulator.
Environmental Considerations Complete recyclability
toughened glass insulators are made of fully recyclable components, so they do not represent a liability when retiring a line from service.
Visual impact - toughened glass insulator easily blend with in the sky
consequently have minimal visual impact once installed on any lines
Applications:
Glass insulator U240BP works as a part of string insulator in transmission lines or substations up to 1000kV , the insulator can assembled as suspension string or tension string with related hardwares .
the insulator string can be single V string , double V string etc.
Competitive Advantage:
The glass insulators has good advantage for example :mass production in auto- production lines , and insulation body of glass component are even and easy for quality control .the unqaulifed parts are recyclable, so it will save cost to provie more reasonable price for end users.
Product quality are very reliable .
insulator shell surface are very smooth and free of visual defect , and easy for maintance in high pollution areas . we offer very competitive price . High quality , best competitive is our goal .
Dalian Hivolt Power System Co., Ltd. ( the former Hivolt Insulators Co., Ltd. ) is a reputable insulator manufacturer. It was set up in year 1990 with product range of porcelain insulators, composite insulators, and relevant metal fittings for transmission & distribution lines.
We look the quality as our company Life, and keep improving products quality. We strictly control the whole manufacturing process according to ISO 9001: 2008 edition, and focus on each quality details from raw material to insulators performance test. The powerful test facilities can make sure that each product under control.
We can supply insulators according to IEC standards, ANSI standards, BS standards or customer specifications. Porcelain glaze can be brown, light gray, white or blue. Composite insulators' shed colour can be light grey or red. In the mean time, we also supply high quality tonghened glass insulators for domestic market and overseas market.
Dalian Hivolt Power System Co., Ltd. is a reputable supplier, we have successfully supplied many kind of insulators to more 30 countries and regions due to reliable quality & reasonable price. We promise if any insulator from our company has quality defect, we will replace them at free charge in 12 months after receipt. We hope to set up a long term cooperation with you and enjoy the course together.
