Product Description

The 33kv High Voltage Polymer Lightning Arrester in Transformer can provide protection systems for transformers in substations and distribution networks. It is suitable for installation in both harsh outdoor environments and outdoors. Our surge arresters use advanced zinc oxide varistor technology to protect transformer insulation from overvoltage caused by lightning strikes and switching operations, ensuring reliable long-term operation. In addition to this, it is housed in a lightweight polymer casing with good hydrophobicity, high mechanical strength and resistance to pollution and UV exposure.

Product FAQ:

Q: Why choose a 33kV high voltage polymer jacketed arrester over a porcelain jacketed arrester?

A: 33kV high voltage polymer-jacketed surge arresters are lighter in comparison and easier to handle and install. They are watertight and reduce the risk of flashover. 3. Less prone to mechanical damage and breakage. Suitable for harsh environmental conditions

Q: How does the 33kV high voltage polymer arrester perform in harsh environments?

A: The polymer shell resists ultraviolet radiation, lasts long and prevents aging. Suitable for use in highly polluted areas, the use of composite materials with high mechanical strength reduces the risk of damage.

Q: What maintenance is required for 33kV high voltage polymer surge arresters?

A: They need to be regularly inspected for signs of wear, contamination or physical damage.

Periodically clean the enclosure to remove dirt or contaminants. Regularly monitor leakage currents and perform insulation resistance tests.

Q: What is a 33kV high voltage polymer arrester?

A: A 33kV high voltage polymer arrester is a surge protection device that protects electrical equipment such as distribution transformers from overvoltage caused by lightning strikes or switching operations. Safety and reliability are enhanced because it uses gapless zinc oxide varistor technology encapsulated in a polymer composite material.
