2.Detailed Capacity Specification Table of Huaquan Box-type Substation

Based on different transformer capacities, Huaquan power box-type substations can be divided into three main specification ranges: klein, medium, and large

The commonly used capacities of Huaquan Power’s box-type substations include 315kVA, 400kVA, 500kVA, 630kVA, 800kVA, 1000kVA, 1250kVA, 1600kVA, ens. Onder hulle, the specifications ranging from 630kVA to 1000kVA are the mainstream choice for power distribution in residential areas.

3. Capacity specifications classified by structural types

Huaquan Power mainly produces European-style box transformers (YB series), and can also customize American-style en Hua-style box transformers according to customer needs.

1. European-style box-type substation (YB series) – Huaquan’s flagship product

The European-style box transformer is a compact, complete set of power distribution equipment that integrates high-voltage switchgear, transformators, and low-voltage power distribution devices according to a specific wiring scheme. It is a flagship product of Huaquan Power.

2. American-style box transformer – compact option

The American-style box transformer integrates the transformer and high and low voltage equipment into a single box design, wat lei tot 'n kleiner grootte en laer koste. It is suitable for industrial parks, tydelike kragtoevoer, en ander scenario's.

3. Huashi box transformer – dedicated for new energy

The Huashi box-type substation is a new type of box-type substation that has developed rapidly in recent years, mainly used in the fields of photovoltaic power generation and wind power generation. The high-voltage switch is independent of the oil tank, making maintenance and repair more convenient.

Huaquan Power can customize Hua-style box transformers according to customer needs, with power options ranging from 630kVA to 4000kVA, suitable for new energy projects of different scales.

4.Capacity Selection Guide

1. Select capacity based on electricity usage scenarios

2. Capacity selection calculation formula

Huaquan Power recommends the following method for preliminary estimation of the required box transformer capacity:

Box transformer capacity (kVA) ≥ total power of electrical equipment (kW) ÷ Kragfaktor (0.8~0.9) × 1.2 (reserved margin)

Berekening voorbeeld 1 – residensiële gemeenskap:

• 500 huishoudings, each calculated at 3kW: 500 × 3kW = 1500kW
• Taking into account the simultaneous coefficient (0.5-0.7): 1500 × 0.6 = 900 kW
• Suggested box transformer capacity: 900 ÷ 0.8 × 1.2 ≈ 1250kVA

Berekening voorbeeld 2 – small and medium-sized factories:

• Total power of equipment: 300 kW (including multiple motors)
• A margin should be reserved for the starting current of the motor
• Suggested box transformer capacity: 300 ÷ 0.8 × 1.5 ≈ 630kVA

3. Precautions for model selection
