Frequently Asked Questions
QWhat is the ZGS-ZT Photovoltaic In-Situ Booster Substation used for?
The ZGS-ZT is a pad-mounted, common tank type three-phase transformer designed specifically for photovoltaic (PV) power generation systems. It boosts the low-voltage DC/AC output from solar panels to medium-voltage grid levels for efficient power transmission and grid connection.
QWhat are the maximum operating altitude and temperature range for this transformer?
The ZGS-ZT can operate at altitudes up to 3000m and within a temperature range of -40°C to +45°C, making it suitable for diverse geographic and climatic environments including high-altitude solar farms.
QWhat voltage classes does the ZGS-ZT transformer support?
The ZGS-ZT supports rated voltage classes of 35kV and below 10kV, with insulation levels designed to withstand power frequency and lightning impulse voltages as specified in the technical parameters table.
QCan the ZGS-ZT be used in harsh or special environmental conditions?
The standard unit is designed for sites free from explosive hazards, chemical corrosion, excessive vibration, and heavy pollution. For applications requiring operation beyond standard conditions, custom configurations are available upon consultation with the manufacturer.
QWhat information is required when placing an order for the ZGS-ZT?
When ordering, customers should provide product ordering drawings including wiring diagrams, transformer capacity, main component model specifications, distribution branch circuits and capacity, requirements for electric energy metering and reactive power compensation devices, compensation capacitor capacity, and surface treatment specifications.
QWhat are the key improvements of the ZGS-ZT compared to previous models?
The ZGS-ZT offers a wider operating temperature range (-40°C to +45°C vs. -25°C to +50°C), higher altitude capability (3000m vs. 1000m), an added wind speed specification (≤30m/s), clarified power quality requirements for balanced 3-phase sinusoidal waveform, and maintained all original safety restrictions.
