It does not say whether it is a high voltage generator or a low voltage generator. This is a low voltage generator (three phase 400 V). It is recommended to use a cable.
< p>A 500 kilowatt generator with a current of about 1,000 amps is laid in the air (ambient temperature 40°), the transmission distance is less than 150 meters. For larger currents, it is more appropriate to use single-phase, single-conductor cables:1. Use YJV 0.6/1kV 1x630 cross-linked polyethylene insulated PVC sheathed power cable (if flame retardant is required). , Add "ZR-" in front of the model, i.e. ZR-YJV 0.6/1kV 1x630
3× (YJV 0.6/1kV 1x630) + 1× (YJV 0.6/1kV 1x630) , a total of 4 cables. Noticed. : When laying cables in the air, each cable must be separated by twice the outer diameter of the cable, and the cables cannot be stacked together
2. parallel core cables, use a cable of aPVC sheathed power supply insulated with cross-linked polyethylene YJV 0.6/1kV 1x240 (if flame retardant is required, add “ZR-” in front of the model, i.e. ZR-YJV 0.6/1 kV. 1x240
3×[ 2 × (YJV 0.6/1kV 1x240)] + 1 × [2 × (YJV 0.6/1kV 1x240)], a total of 8 cables. Please try to separate. the cables and do so do not stack them together, which promotes heat dissipation from the cables themselves
In addition, the generator can be connected to a larger galvanized flat iron

What size generator should be used for general household use?
The power of the machine is usually 1900 W. There are four types of automobile generators: 1. Ordinary alternator: also called silicon rectifier generator, which requires a voltage regulator when used 2. Integrated alternator: the generator and regulator are transformed into an integrated generator For example, the Buick car engine is.equipped with a CS type generator, including three different models: CS-121, CS-130 and CS-144; . AC Generator with Pump Machine: The pump installed in the alternator with a pump is a vacuum pump, not a vacuum booster pump. Vacuum booster pump is used in car brake system. 4. Brushless alternator: a generator that does not require a pump. brushes.
Generally, a 5KW generator is sufficient for domestic use. If it can be reduced by 2KW for some electrical appliances, it will be enough
The specific calculation method based on. Common electrical appliances are:
1. Power level of common household appliances:
Microwave oven 600----1500 watts
Rice cooker 500- ---1700 watts
Induction cooker 300----1800 watts
< p>Electric wok 800----2000 wattsElectric water heater 800-- --2000 watts
< p>Refrigerator 70----250 wattsElectric heating 800----2500 watts
Electric oven 800----2000 watts
Sterilizer 600----800 watts< /p>
Electric iron 500- -- -2000 watts
Air conditioner 600----5000 watts
Air conditioner 1000W
Micro oven waves 1000W
Electric cooker 1000W
Electric water heater 1000W
Vacuum cleaner 800W
Hair dryer 500W
500W electric iron
500W washing machine
200W TV
200W computer
140W kitchen hood
100W fan
0.5W flashlight< /p>< p>50-100W lighting
2. Calculate the power of electrical appliances that must be used during a power outage
250W refrigerator
TV. 200W
200W computer
50-100W lighting
The starting battery box is a compressor, and the starting current is calculated as 2.5 times , so the power of the refrigerator generator is 250*2.5=625W
Thus, the powerminimum of a domestic generator is 200+200+100+625=1125W, which leaves some power available, so a 2KW generator is enough!
3. Calculating the power of commonly used electrical appliances
Some families can add air conditioners, electric water heaters and other equipment to the necessary electrical appliances:
Because air conditioners are tablets, the starting current of the air conditioner is also calculated based on 2.5 times. A 1000 W air conditioner requires a generator power of 2500 W. Plus the 1000 W power of the electric water heater, plus the 2000 W power of the essential original electrical appliances.
So commonly used generators in home appliances are 1125W + 1000W + 2500W = 4625W, which leaves a bit to spare. 5KW generators are enough!
