As a leading manufacturer in the electrical equipment industry, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our U70BS 210 Transparent Glass Insulator. Engineered for the demanding environments of high-voltage (HV) transmission lines, this product embodies our commitment to reliability and performance. With over a decade of experience and a steadfast adherence to the ISO9001 quality management system, we have developed this insulator to provide superior lightning protection and long-term operational stability for power grids worldwide. Our product is a direct result of understanding the critical need for durable components that minimize maintenance and ensure uninterrupted power flow across continents.
The U70BS 210 is specifically designed for suspension applications on overhead transmission lines. Its core function is twofold: to provide robust electrical insulation between the live conductor and the transmission tower, and to offer enhanced protection against lightning strikes, a major cause of power outages. The use of high-quality tempered glass gives it distinct advantages over traditional materials.
- Exceptional Durability: The toughened glass construction offers high mechanical strength, capable of withstanding significant mechanical loads from the conductor and environmental forces like wind and ice.
- Superior Electrical Performance: It maintains excellent dielectric properties under various weather conditions, ensuring stable insulation performance.
- Self-Cleaning Surface: The smooth, non-porous surface of the glass sheds water effectively and resists the accumulation of dust, salt, and industrial pollutants. This "hydrophobic" characteristic helps maintain insulating performance in polluted environments, reducing the risk of flashovers.
- Transparency for Easy Inspection: The clear glass body allows for quick visual inspection of the insulator's integrity. Any cracks or damages are immediately visible, enabling proactive maintenance and replacement, which enhances grid safety.
- Zero Degradation: Unlike some composite materials, glass does not age or degrade due to ultraviolet (UV) radiation from sunlight, ensuring consistent performance over its entire service life.
- Fire Resistance: Being an inorganic material, glass is completely non-combustible, adding an extra layer of safety to the transmission infrastructure.
For our global clients in regions like North America, Southeast Asia, Europe, and Africa, this translates into a lower total cost of ownership. Reduced cleaning frequency, minimal maintenance needs, and long service life directly contribute to more economical and reliable power transmission operations.
Below is a summary of the key technical specifications for the U70BS 210 Insulator:
| Parameter | Specification / Value |
|---|---|
| Model Designation | U70BS 210 |
| Rated Mechanical Load (SML) | 70 kN |
| Creepage Distance | Approximately 210 mm (Customizable) |
| Insulation Material | Tempered (Toughened) Glass |
| Structure Type | Suspension Disc Insulator |
| Application Voltage | High Voltage (HV) Transmission Lines |
| Connection Type | Ball & Socket (Standard), other types available |
The "210" in the model name typically refers to a key structural dimension, such as the nominal diameter or a standardized creepage distance, which is crucial for pollution performance. The ball and socket connection ensures secure linkage within an insulator string, providing flexibility and reliability.

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of a glass insulator over a porcelain one?
A: Glass insulators offer easier visual inspection for damage (cracks are very visible), generally have higher mechanical strength, and possess a self-cleaning surface that performs well in polluted conditions, potentially reducing maintenance.
Q2: How does the U70BS 210 provide lightning protection?
A: It is part of the insulation system that increases the overall insulation strength of the transmission line. By providing a high-impedance path, it helps control and mitigate the overvoltages caused by lightning strikes, protecting the line and connected equipment.
Q3: What does the "70" in U70BS stand for?
A: The "70" typically denotes the Specified Mechanical Load (SML) in kilonewtons (kN). A 70 kN rating means the insulator is designed to withstand a tensile load of 70 kN, indicating its mechanical strength.
Q4: Can this insulator be used in coastal or heavily polluted industrial areas?
A: Yes. The tempered glass material and the designed creepage distance (e.g., ~210mm) help it resist the effects of salt fog and industrial pollution. Its smooth surface prevents contaminant buildup, maintaining performance.
Q5: Are the metal fittings (ball & socket) included, and what are they made of?
A: Yes, the insulator is supplied as a complete unit with galvanized cast iron or malleable iron fittings as standard, providing corrosion resistance. Other materials like hot-dip galvanized steel can be specified.
Q6: What is the expected service life of this glass insulator?
A: When installed correctly and under normal operating conditions, glass insulators can have a service life exceeding 30 years due to their resistance to aging from UV light and environmental factors.
Q7: Do you offer different creepage distances for varying pollution levels?
A: Yes. While the U70BS 210 has a standard creepage, we can provide insulators with longer creepage distances for areas with higher pollution severity (e.g., Heavy Industrial or Coastal zones).
Q8: What packaging is used for export shipment?
A: We use robust, weather-resistant wooden crates or pallets to ensure the insulators arrive undamaged. Packaging is designed to withstand long-distance sea freight, which we manage from major Chinese ports.
