Frequently Asked Questions (FAQS)
What is a porcelain lighting housed arrester and how does it function?
A porcelain lighting housed arrester is a surge protection device that safeguards electrical equipment from over-voltage transients caused by lightning strikes or switching operations. It features a durable porcelain housing encasing metal-oxide varistors (MOVs). When a surge occurs, the MOVs rapidly reduce their resistance, creating a low-impedance path that safely diverts surge energy to ground, protecting connected equipment.
What are the key advantages of porcelain housed arresters?
Porcelain housed arresters offer high mechanical strength and durability, excellent performance in high-contamination environments, long service life, and proven reliability under extreme weather conditions. They are maintenance-free and provide consistent overvoltage protection.
In what applications are porcelain lighting arresters typically used?
They are commonly used in high-voltage substations, transmission lines, industrial power systems, and areas with high pollution levels. They protect transformers, circuit breakers, and other critical infrastructure from lightning and switching surges.
How do your porcelain arresters perform in harsh environmental conditions?
Our porcelain-housed arresters withstand extreme temperatures from -40°C to +70°C, high humidity, UV exposure, and chemical pollutants. The robust porcelain housing provides excellent mechanical strength, insulation, and extended creepage distances, making them ideal for polluted, coastal, or industrial environments without requiring maintenance.
What maintenance is required for porcelain lighting arresters?
Maintenance includes regular visual inspections for physical damage, contamination, or signs of electrical discharge. Cleaning of the porcelain surface may be needed in polluted areas, and periodic testing of electrical performance, such as leakage current measurements, is recommended.
How do porcelain arresters compare to polymeric surge arresters?
Porcelain arresters are known for their mechanical strength and durability, making them suitable for harsh environments, but they are heavier and more prone to shattering. Polymeric arresters are lighter, more resistant to environmental degradation, and offer better shatter resistance.
What factors should be considered when selecting a porcelain lighting arrester?
Key factors include the maximum continuous operating voltage (MCOV), rated voltage, energy absorption capacity, nominal discharge current rating, environmental conditions (e.g., pollution levels, temperature), and specific application requirements such as for substations or transmission lines.
How do you ensure standards compliance and long-term reliability for critical infrastructure?
Our arresters are manufactured under strict quality control with rigorous raw material selection and multi-stage testing. They comply with international standards such as IEC 60099-4 and ANSI/IEEE C62.11, and have passed third-party tests including SGS evaluations. Each unit undergoes energy withstand tests, classification, and accelerated life testing to ensure consistent performance and durability for grid applications.
What is your manufacturing capacity and lead time for large volume orders?
We have substantial production capacity with 17,000 square meters of production space and 5,000 square meters of warehousing, supported by automated processes. We can supply high volumes annually and typically deliver within 25 days from contract signing, ensuring on-time delivery for bulk orders from EPC contractors or distributors.
Do you offer custom manufacturing or OEM services?
