 ●Ambient Temperature: Maximum +55°C, Minimum -45°C

 ●Humidity: Daily average relative humidity not exceeding 95%; monthly average not exceeding 90%

 ●Wind Speed: Outdoor wind speed not exceeding 45m/s

 ●Seismic: Horizontal acceleration ≤0.4m/s², vertical acceleration ≤0.15m/s²

 ●Installation Site Inclination: Not exceeding 3°

 ●Installation Environment: Surrounding air free from significant pollution by corrosive or flammable gases; no severe vibration at installation site

Note: If your order exceeds the above conditions, please consult with our company.

Functions and Features

 ●Combines the advantages of both European and American style substations, making it more suitable for wind/photovoltaic power plants

 ●HV side equipped with HV vacuum load switch-fuse combination apparatus, integrated vacuum circuit breaker, or solid-sealed pole circuit breaker

 ●Isolation blade, arc extinguishing chamber, and fuses are placed in separate compartments, truly enabling individual unit maintenance without shutting down other turbines

 ●HV switch to transformer connection uses busbars instead of cables, eliminating operational safety issues associated with cable connections

 ●Transformer radiators are installed in an open configuration with natural ventilation for heat dissipation, saving substantial energy loss from forced-air cooling and eliminating the risk of overheating trips due to unreliable fan performance

 ●Transformer oil level gauge, gas relay, pressure relief device, etc. are all exposed externally for intuitive observation of transformer operating conditions

 ●Complete protection functions

 ●Substantial copper savings, lower overall cost, and reduced user investment

Information Required for Inquiry or Order

Please provide the following accurate information when making an inquiry or placing an order, so that we can perform technical calculations and production scheduling:

 ●Project Overview: Project name, installation location, service environment (e.g., altitude, max/min temperature, relative humidity, pollution level, presence of corrosive gases or severe vibration, etc.)

 ●Product Model & Specifications: Specify the required Chinese-style box substation model (e.g., ZYBH series) and transformer rated capacity (kVA)

Transformer Configuration:

 ●Transformer type

 ●Rated capacity (kVA)

 ●HV and LV rated voltage levels (e.g., 35kV/0.4kV or 10kV/0.4kV)

 ●Rated frequency (50Hz or 60Hz)

 ●Winding material: Copper or Aluminum

Appearance & Dimensions: Specify enclosure material (e.g., composite anti-corrosion material, aluminum-zinc coated steel plate + ceramic coating, etc.), color (provide color card number or RAL code), roof style, and overall dimension limitations (if any site constraints exist)

Protection Level: Specify IP protection level requirements for HV compartment, LV compartment, and external transformer (e.g., all live parts fully sealed, protection level up to IP67, etc.)

Key Technical Parameters & Configuration Requirements

 ●HV Side Configuration: Specify HV side voltage level, incoming line method (cable/overhead), HV switchgear selection (e.g., solid-insulated fully enclosed switchgear, gas-insulated switchgear, vacuum circuit breaker, etc.), protection configuration (e.g., isolation blade, arc extinguishing chamber and fuse separate compartment configuration, microcomputer-based comprehensive protection device, etc.), and metering method (high-voltage supply with high-voltage metering / high-voltage supply with low-voltage metering)

 ●LV Side Configuration: Specify LV side voltage level and number of outgoing feeders, main switch and branch switch brands, specifications, and parameters; reactive power compensation capacity and switching method (e.g., intelligent capacitor compensation); intelligent monitoring instruments and communication interface requirements (e.g., RS485, Ethernet, Modbus protocol, 5G communication module, etc.)

 ●Temperature Control & Lighting: Specify transformer heat dissipation method (e.g., open radiator with natural ventilation, top oil pump circulation + side wall radiator combination, etc.), automatic lighting for each compartment, and maintenance socket configuration requirements

 ●Special Function Requirements: If anti-condensation devices, fire alarm systems, video surveillance systems, remote monitoring terminals (DTU/FTU), partial discharge monitoring, oil chromatographic analysis, or other condition-based maintenance functions are required, please specify in writing in advance

Ordering Process & Precautions

 ●Technical Agreement: For non-standard products or complex projects, both parties must sign a detailed Technical Agreement before production scheduling, which shall serve as an annex to the contract with the same legal effect

 ●Drawing Confirmation: We will provide appearance drawings, foundation drawings, and single-line diagrams of the Chinese-style box substation according to your requirements. Please sign and confirm promptly. Any schedule delays resulting therefrom shall be borne by your side

 ●Change Management: After order confirmation and drawing signature, any technical or commercial changes must be submitted in writing and can only be executed after mutual re-confirmation. Cost increases or schedule delays caused by changes shall be borne by the requesting party

 ●Site Coordination: Please ensure that on-site foundation construction is carried out strictly according to the foundation drawings we provide, with sufficient space reserved for lifting and transportation access. If you require on-site installation guidance or commissioning services, please schedule in advance
