Wire load is everyone in the purchase of wire are more concerned about, the current life of the more commonly used wire specifications are 1 square wire, 1.5 square wire, 2.5 square wire, 4 square wire, 6 square wire, so these wires can load how many watts? This is also the concern of everyone. Here is a detailed look at 1, 1.5, 2.5, 4, 6 square wires can load how many watts.

1, 1 square wire can load how many watts

An electrician's commonly used "empirical formula" : as long as it is a copper wire, the cross-sectional area of each square millimeter can safely pass the rated current of 4-5A; In the 220V single-phase circuit, the current is about 4.5A per 1KW power; In the 380V three-phase balanced circuit, for every 1KW of power, the current is about 2A. These values above, the results of the physical calculation formula can be calculated is very close, so the electrician in the work, in order not to remember those "cumbersome" calculation formulas, just remember these. Then according to this algorithm, it is known that a copper core wire with a cross-sectional area of 1 square millimeter, if used in a 220V single-phase circuit, can safely carry the current passed by a 1KW load; If used in a three-phase balanced load (such as a motor) circuit, it can safely carry the current passed by a 2.5KW load.

Two, 1.5 square wire can load how many watts

If the power cord is a copper core wire, the allowable working current of the open wire installation is 20A, that is, 4400 watts; The second is the hidden sleeve steel pipe, the current is 16A, the power is 3520 watts; Third, the pvc pipe is concealed, the current is 14A, then the power is 3000 watts.

Three, 2.5 square wire can load how many watts

How many kilowatts of power is the 2.5 square wire function, the national standard GB4706.1-1992/1998 wire load current value, copper wire 2.5 square mm 16A ~ 25A about 5500 watts, Aluminum core wire 2.5 square mm 13A ~ 20A about 4400 watts 220VAC voltage for a long time does not exceed 10A standard most of the time does not exceed 15A is safe.

Four, 4 square wire can load how many watts

Single-phase power supply 1KW is about 4.5A, 8KW is about 36A. 4 square wire (single plastic copper wire) carrying capacity is about 30A, smaller, change 6 square lines (single run power supply). Your watch and gate must be larger. It doesn't have to be that big. 4KW, that's fine. How many kilowatts of power a 4 square wire can take depends on whether you have a 220v home or a 380v factory if a 220 4 square wire can carry 6 to 8 kilowatts.

Five, 6 square wire can load how many watts

6 square wire can load how many kilowatts of power line diameter and transmission of power is not directly related. Generally speaking, 6 square wires are more than enough for air conditioning wires. The maintenance power supply on the construction site is generally 10x6+1x4 cable. As for the current strength, according to my construction experience, this cable is generally controlled by a 63A air switch. 6 square aluminum wire can load 6 kilowatts 6 square copper wire can load 10 kilowatts.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
