Ultra high voltage and ultra-high voltage partial discharge (impact) shielding test hall

The ultra-high voltage and ultra-high voltage partial discharge (impact) shielding test hall (factory) is suitable for various voltage levels such as cables, transformers, transformer switches, and power stations（Partial discharge test or impulse test for 110KV, 220KV, 500KV, 750KV.

Based on the characteristics of a large shielding test hall (factory building), we have independently developed shielding structures and processes suitable for different testing requirements of cables, transformers, and mutual inductors. These structures have excellent cost performance, high quality, flat and beautiful appearance, and long service life. The shielding design scheme has been recognized and recommended by authoritative domestic design institutes.

The airtight shielding doors in the shielding test hall are divided into two categories: sliding doors and lifting doors. Platform screen doors are the key to shielding halls, and airtight shielding overcomes many of the shortcomings of traditional shielding structures. Its advantages include excellent performance, easy operation, reliability, long service life, low maintenance rate, and low maintenance costs.
