Pin Insulator – Rax Industry

Product Details: Pin insulators are used in power distribution systems, mounted to electrical cross arms of utility poles with bolts or pole top pins. They are assembled on top of electrical poles or towers, with conductors fixed to the grooves using top ties. Pin insulators can be made of ceramic, porcelain, polymer, glass, or silicon rubber. They are suitable for voltages up to 33kV, with one-piece types for lower voltages and two or three-piece types for higher voltages.

Pros:
– Low price
– High mechanical strength
– Simple design
– Easy maintenance

Cons:
– Bulky and expensive for voltages beyond 33kV

Frequently Asked Questions (FAQs)

What is the typical voltage capacity of pin insulators produced in China?

?

Pin insulators made in China are generally designed to handle voltage capacities up to 33 kV. These insulators are widely used in power distribution systems for voltages within this range, ensuring safe and efficient transmission of electricity.

What materials are commonly used to make pin insulators in Chinese factories?

?

Chinese factories typically produce pin insulators using materials such as porcelain, ceramic, polymer, glass, or silicon rubber. Porcelain is one of the most common materials due to its high mechanical strength, good anti-pollution performance, and competitive pricing.

How are pin insulators installed and used in power transmission systems?

?

Pin insulators are installed on the cross arms of utility poles or towers. The conductor is fixed to the grooves on the upper end of the insulator using a top tie or side tie. This setup ensures the conductor is isolated from the supporting structure, preventing electrical current from flowing to the ground.

What are the key features and benefits of pin insulators made in China?

?

Pin insulators from Chinese factories are known for their high mechanical strength, good anti-pollution performance, and simple design, which makes them easy to maintain. They are also relatively affordable and can be used in both vertical and horizontal orientations, making them versatile for various applications.

Do Chinese pin insulator manufacturers adhere to international standards and quality certifications?

?

Yes, many Chinese pin insulator manufacturers adhere to international standards such as IEC and ANSI, and they often hold quality certifications like ISO9001, ISO14001, and ISO45001. This ensures that the products meet high quality and safety standards.
