Product Use

For ground-level utility and industrial distribution, product Use is treated as a practical design and selection point rather than generic catalog wording.

• ZBW-12/0.4 pre-installed substation is a type of American-style prefabricated box-type substation. As an integrated prefabricated product, it combines the cable of the distribution network power supply unit, high-voltage control and protection devices, substation components, and power distribution equipment. It is widely used in urban and rural power distribution networks.
• The product is equipped with high-voltage load switches and high-voltage fuses in the transformer oil tank, and has two structural forms: integrated transformer tank and separate transformer tank. The tank adopts a fully sealed structure, and is equipped with oil temperature gauges, oil level gauges, pressure gauges, pressure release valves, drain valves, and other components to monitor the operation status of the transformer.
• According to the power supply mode, the product is classified into ring network type and terminal type. To make this product more suitable for the actual requirements of China's power grid, the company has also launched plug-type fuses, which do not affect the performance of transformer oil.
• Based on the complexity of low-voltage outgoing circuits, ZBW-12/0.4 products are divided into three cabinet types: standard type, enhanced type, and comprehensive type. This allows users and design units to make more flexible and cost-effective selections.

Model Description

For ground-level utility and industrial distribution, model Description is treated as a practical design and selection point rather than generic catalog wording.

• Taking the ZBW series as an example, the model is represented as ZBW - 12/0.4 - □ - □ - □.
• The first part "ZBW" indicates the prefabricated substation.
• "12/0.4" represents the rated voltage levels, with 12kV for the high - voltage side and 0.4kV for the low - voltage side.
• The subsequent boxes respectively denote the high - voltage measurement of rated voltage (KV), low - voltage measurement of rated voltage (KV), and rated capacity of the transformer (KVA).

Use Environment

For ground-level utility and industrial distribution, use Environment is treated as a practical design and selection point rather than generic catalog wording.

• Environmental temperature: Maximum temperature +40℃, minimum temperature -30℃ 2. Altitude: ≤1000m (Note: The original "s1000m" is corrected to "≤1000m", which is the conventional expression for "altitude not exceeding 1000m" in technical documents) 3. Wind speed: Equivalent to 34m/s (wind pressure not exceeding 700Pa) 4. Humidity: Daily average relative humidity shall not exceed 95% (Note: The original repeated "the relative humidity of the average value is no more than 95%" is deleted to eliminate redundancy; "Dally" is corrected to "Daily") 5. Earthquake: Horizontal acceleration shall not be greater than 0.4m/s²; vertical acceleration shall not be greater than 0.15m/s² (Note: "Earthauake" is corrected to "Earthquake"; "the level of acceleration" is specified as "horizontal acceleration" to avoid ambiguity) 6. Slope of installation location: No more than 3° (Note: The original "3° degrees" is corrected by deleting "degrees", as "°" already represents the unit of angle, avoiding repetition) 7. Installation environment: The surrounding air shall be free of corrosive substances, flammable gases, and other obvious pollutants; the installation site shall be free of severe vibration (Note: "is not corrosive" is adjusted to "free of corrosive substances" to accurately describe the absence of harmful media; "other obvious polution" is corrected to "other obvious pollutants") 8. If customers need to order products that exceed the above conditions, they can negotiate with the company (Note: The original "order the product beyond the above conditions" is adjusted to a conditional sentence for logical smoothness; "the company can negotiate with the company" is corrected to "they can negotiate with the company" to eliminate ambiguous reference to "the company").

Product Advantages

For ground-level utility and industrial distribution, product Advantages is treated as a practical design and selection point rather than generic catalog wording.

• Compact structure and small size: Its volume is only about 1/3 to 1/5 of that of domestic European-style box-type substations with the same capacity, greatly reducing the floor area. (Note: "grealy" is corrected to "greatly"; the subject "its volume" is added to complete the sentence, clarifying the comparison object as "the volume of European-style box-type substations with the same capacity"; "area" is refined to "floor area" to better fit the technical scenario of "floor space" and avoid ambiguity.).
• Fully sealed and fully insulated structure: It requires no insulation distance and provides reliable personal safety protection. (Note: "fuly" is corrected to "fully"; "without the need of insulation distance" is optimized to "requires no insulation distance", which conforms to the concise expression habit of English technical documents; "reliable protection of personal safety" is adjusted to "provides reliable personal safety protection" with the predicate "provides" added to make the sentence structure complete and logically coherent.).
• Flexible high-voltage connection and power supply mode: The high-voltage connection can be used for both ring network and terminal connections, featuring flexible power supply mode and high reliability. (Note: "fiexible" is corrected to "flexible"; the repeated expression "can be used for the ring network, and can be used for the terminal" is merged into "can be used for both ring network and terminal connections" to simplify the sentence structure; "featuring" is used to connect "flexible power supply mode" and "high reliability", making the characteristic description more compact.).
• Excellent transformer performance: The transformer has excellent performance, with low loss, low noise, and low temperature rise. It also has strong overload capacity, as well as short-circuit and impact resistance. (Note: "the transformer performance excellence" is adjusted to "excellent transformer performance", which conforms to the common English structure of "adjective + noun"; the predicate "has" is added to correct the incomplete component issue of "overload ability, short circuit, impact resistance", clarifying that it "has strong short-circuit and impact resistance", making the performance description more complete and accurate.).
• Adaptable to low-voltage outgoing requirements: It can meet the requirements of various low-voltage outgoing circuits, and can be selected according to existing schemes or customized as required. (Note: The subject "it" is added to complete the sentence; "low voltage feed" is optimized to "low-voltage outgoing circuits" (a more accurate professional term for "low-voltage outgoing circuits"); the logical fault in "can be selected according to the scheme, but also to design" is corrected, and "or customized as required" is used to clarify the meaning of "can be designed on demand", which fits the common expression of "customization" in technical documents.).
• Two types of cable connections available: There are two options for cable connections: cable head plugs and 200A/600A elbow-type "T"-shaped fixed cable joints. A fully insulated zinc oxide arrester can be configured; the 200A cable head supports live plugging and serves as an isolating switch. (Note: "arrestel" is corrected to "arrester" (a professional term for "lightning arrester"); the confused word order in "cable head plug and 600A 200A elbow type 't' type fixed cable joint two" is adjusted to clarify the classification of "two types of cable connections"; "can take load plug and play a role in isolating switch" is optimized to "supports live plugging and serves as an isolating switch", where "live plugging" is a standard expression in the power equipment field, and "serves as" makes the logic of "also functioning as an isolating switch" clearer.).

Product Structure Features

For ground-level utility and industrial distribution, product Structure Features is treated as a practical design and selection point rather than generic catalog wording.

• Transformer and Chambers: The pad-mounted transformer uses the 813 series oil-immersed transformer with a chip-type oil tank (no oil cushion, fully enclosed). High/low-pressure bushings, tap changers, oil level indicators, pressure release valves, oil release valves, etc., are mounted on the high-pressure chamber end plate for easy observation and operation. Its high/low-pressure chambers are separated by steel plates (relatively independent) and integrated into a complete box.
