Welcome to visit our Factory!
Brief Introduction
Bonle (Fujian) Insulator Co., Ltd. is a leading insulators manufacturer in China, with over 20 years of experience.
Formerly known as BONLE (MINQING) LOW VOLTAGE ELECTRIC CO., LTD., our company was established in November 2006. It began as our first porcelain insulators factory, located in Minqing, Fujian, China.
With a registered capital of RMB 20 million and a total investment of RMB 50 million, our facility covers an area of 23,000 square meters, with a building area of 18,000 square meters. We own a high-standard workshop and a very wide space, creating superb conditions to produce high-voltage porcelain insulators.
As a professional insulators manufacturer, we focus on continuous growth and expansion.
In May 2013, we invested to build our second porcelain insulator factory, FUJIAN NEW BONLE INSULATOR CO., LTD. In March 2014, our new factory was established with a total investment of RMB 100 million. It has a floor area of 80,000 square meters and a structure area of 60,000 square meters. As a result, we have become one of the largest line insulators and electric power fittings manufacturers in China.
Our Main Products
We are a leading specialized insulators manufacturer offering various high and low voltage porcelain insulators, glass insulators, composite insulators, and electric power fittings. Our product range includes 210kN, 160kN, and below suspension porcelain disc insulators, fog type disc suspension insulators, pin type insulators, line post insulators, insulators for cross arms, strain insulators, spool insulators, shackle insulators, post and hollow insulators under 35kV, and more than 1,000 other kinds of insulators.
Technical Strength and Innovation
We possess strong technical strength in the insulator field. Our team consists of 35 senior and medium engineers and approximately 580 employees.
Our manufacturing technology adopts advanced domestic semi-automatic production lines. We use clean gas as fuel and world-advanced energy-saving oxide flame firing. Meanwhile, we operate physics and chemistry labs and high-voltage electrical labs. We have established and strengthened a strict production technology and quality guarantee control system.
We are currently cooperating with the Jingdezhen Ceramics Institute to research high-strength formulas for oxide flame firing. After success, we will be able to produce over 210kN porcelain disc suspension insulators for high voltage, filling the gap of high-voltage and high-tonnage products in Fujian Province. We also joint with Fuzhou Porcelain Industry Technology Innovation Center to establish the “Fujian Province Electrical Porcelain Industry Technology Innovation Base — Bonle Electrical Porcelain Research and Development Center”.
Why Choose Bonle as Your Insulators Manufacturer
Our products strictly comply with the standards of IEC, BS, ANSI, and GB. Our company follows the spirit of enterprise: “CUSTOMERS RESPECTED AS GOD, QUALITY FIRST, HONESTY AND CREDIT, TECHNOLOGY PROSPECT ENTERPRISE” to reward all clients.

Production Equipment for Glass Insulator
MOLDING SYSTEM
Automatic ingredients system: Sanrui’s fully automatic batching system enables static precision to reach 0.01%, the dynamic precision 0.3% and the batching evenness over 99%. In terms of these indexes, the system has reached the advanced level in this industry.
MOLDING SYSTEM
Electronic servo feeder machine is suitable for products of large tonnage with gob weight deviation of +/-10g. 12-station press has notably promoted output, post forming technology of Sanrui is domestically superior.
FURNACE
The latest technology efficiently reduce the energy consumption, fulfill environmental protection and energy-saving cleaner production. Such furnace is characterized by advanced structure, easy to control, high melting rate and great glass fluid evenness.
TEMPERATURE WELL-DISTRIBUTED FURNACE
Five-section heating furnace improves the effect of heat treating
and creates favorable conditions fortempering.
FURNACE
20-station tempering machine is configured with telescopic lower ventilation grid, which can improve the quality of tempering.
THE NICKEL SULFIDE PROCESSING LINE
Domestic advanced nickel sulfide processing line is adopted to effectively remove nickel sulfide to further reduce the rate of self-shattering.
THE IMPACT OF HOT AND COLD LINE
The impact of hot and cold line: All glass pieces have to experience cold and heat shock for three times to minimize the rate of self-shattering. The temperature difference in thermal shock must to be larger than 370K while that in cold shock must to be larger than 110K.
PRODUCT ASSEMBLY
10000Hz high-frequency vibration glass cementing and water
curing technology are adopted to ensure the quality.
