ZS, ZB, ZD series high-voltage line column insulators: Indoor column insulators are used for insulation and fixed conductors in high-voltage electrical appliances or indoor distribution equipment.
All performance indicators comply with the provisions of GB8287-87.
2. Outdoor rod-shaped pillar insulator
Outdoor rod insulators are used for insulation and fixing of conductive parts in outdoor high-voltage distribution equipment and electrical equipment with rated AC voltage of 10-500KV. They are divided into two categories: ordinary type and pollution resistant type.
The ZS, ZB, ZD series high-voltage line column insulators meet the requirements of GB8287.2-87 and GB12744-91 standards in all indicators.
