Product Overview & Application Scenarios
Overview:
Goldhome has rich experience and mature technical support in high voltage partial discharge shielding rooms, providing high-quality products and reasonable prices.
High Voltage Partial DIscharge for Test Shielded Room is a precision testing facility designed to detect partial discharge (PD) phenomena in high - voltage electrical equipment. By capturing high - frequency signals, it ensures accurate monitoring. Comprising a detection system and a shielding system, it integrates electromagnetic shielding, insulation protection, and signal amplification functions, guaranteeing both safety during testing and data reliability.
⚫ Test Subjects: Switchgear, voltage and current transformers, organic composite insulators, cables, generators, etc;
⚫ Test Items: Support for partial discharge testing;
⚫ Compliance Standards: GB12190-2006 Measurement Methods for Shielding Effectiveness of Electromagnetic Shielding Rooms.

Equipment Features
1. The shielded room floor employs a new construction method requiring no excavation or internal concrete pouring. The interior floor is only approximately 2 cm higher than the exterior, ensuring unimpeded access for personnel and forklifts.
2. A combination of modular assembly and welding facilitates relocation and disassembly while maintaining shielding performance.
3. Exterior walls are clad with premium tongue-and-groove sandwich panels made of fire-resistant and flame-retardant materials, adding an aesthetically pleasing decorative layer;
4. Control room flooring utilizes high-quality composite flooring for a premium, sophisticated appearance.
