Product Introduction
Core Advantages
Excellent transmission efficiency: through step-up transmission, the line current is effectively reduced, the loss of long-distance transmission is greatly reduced, and the overall energy efficiency of the power grid is significantly improved.
Large-capacity carrying capacity: it adopts high-permeability silicon steel sheet and high-quality copper/aluminum winding design, which has strong short-circuit resistance and overload resistance to meet the needs of large-load electricity consumption.
High reliability and long life: combined with advanced insulation structure and vacuum oiling technology, it ensures long-term stable operation of the equipment in harsh environments and extends its service life.
Low loss and energy saving: it meets national first-level energy efficiency standards, has low no-load and load losses, and significantly reduces the operating electricity costs throughout the life cycle.
Intelligent monitoring (optional): Support integrated online oil chromatographic analysis, temperature, pressure and partial discharge monitoring system to realize status maintenance and fault early warning.
Applicable Scenarios
EHV/HV Transmission
It is used in UHV and ultra-high voltage hub substations and is responsible for the long-distance transmission of clean energy sources such as hydropower and wind power in the west to the load center in the central and eastern regions. It is the core equipment of the national "West-to-east transmission" and "North-to-south supply" strategies.
01
Renewable Energy Integration
It is specially designed for gigawatt-level wind farms and photovoltaic power plants to solve the pain points of large fluctuations in the output of new energy and long distances from the main network, and to achieve stable boost and smooth access of clean energy from the collector circuit to the high-voltage main network.
02
Heavy Industry & Industrial Parks
It serves dual-loop or multi-loop power supply scenarios such as steel mills, petrochemical parks, and large manufacturing bases, and provides high short-circuit impedance and strong anti-disturbance power supply support for impact loads such as electric arc furnaces and rolling mills.
03
Urban Grid Expansion
In view of the limited space of substations in the central urban areas of first-tier cities, a compact and low-noise design solution is provided to solve the power supply bottleneck and neighborhood avoidance effect caused by the surge in urban load.
04
Critical Infrastructure
Provide N+1 redundant power supply guarantee for national-level data centers, international airports, and rail transit hubs to ensure uninterrupted operation under extreme weather or power grid fluctuations.
