Frequently Asked Questions (FAQ)
Q1: What is the main material of the U70BS insulator?
A1: It is made of high-strength toughened glass, which offers excellent mechanical strength, thermal shock resistance, and self-cleaning properties.
Q2: Can this insulator be used for high-voltage lines other than lightning arrestor systems?
A2: Yes, while it is optimized for lightning arrestor applications, the U70BS can also be used in general overhead transmission lines as a suspension or tension insulator, provided the electrical and mechanical requirements match.
Q3: What is the meaning of the mechanical load rating of 70 kN?
A3: It indicates the maximum static load the insulator can withstand without breaking. This rating is typically tested as the electromechanical failing load, ensuring safe operation under normal and extreme conditions.
Q4: Does the 210 mm creepage distance meet the requirements for heavy pollution areas?
A4: Yes, 210 mm creepage distance provides a good balance between size and pollution performance. For severe pollution environments, longer creepage distances may be necessary; we can provide custom options upon request.
Q5: What connection types are available for this insulator?
A5: The standard connection is ball and socket with a 16 mm pin. Clevis tongue or other custom interfaces are available as optional configurations.
Q6: Do you provide quality certifications?
A6: Yes, we offer various certifications such as ISO9001, ISO14000, OHSAS18001, and others. Specific certification documents can be provided upon request for your project.
Q7: What is the typical lead time for an order of U70BS insulators?
A7: Lead time depends on the quantity and customization. For standard products, it is usually 15–25 working days after order confirmation. We can expedite for urgent orders.
Q8: How do you ensure the product quality during shipping?
A8: Each insulator is individually packed with foam or wooden crates to prevent breakage. We use professional packaging and have experience exporting to many countries with minimal damage.
