Power cord is an indispensable household product in daily life. It can be seen everywhere, which also adds a lot of convenience to our life. However, if you want to buy power cord, you must choose the official authentic product, because the inferior Sanwu brand is cheap

British power cord is also called British power cord, which is a power plug cord with British BS standard as reference standard. The plug of British power line can be divided into assembly type and injection type. The assembly type British plug can be disassembled, and various specifications of power line can be customized freely, while the injection type is generally integrated and can not be disassembled. The common British Standards on the market are bs1363, bs546, bs5733, etc., which stipulate the standards that a product must follow when entering the UK.

The European standard power cord is European AC power cord, the plug is Schuko CEE 7 / 7, belongs to D type plug, the current is 16 A, the voltage is 250 V, the plug has two pole plug and three pole plug, and the three wire plug has grounding.

People who have been in contact with the wire and cable industry know more or less that there are national standard lines and non-standard lines in the wire and cable industry. The existence of non-standard line has seriously threatened the safety of people's lives and property, and many tragic fires caused by non-standard line are always alerting us. Non standard line is not only a problem in the wire and cable industry, but also a problem closely related to people's lives and property. It is our duty to strike and resist non-standard line.

A power line is a wire that transmits current. Generally, the mode of current transmission is point-to-point transmission. Power line can be divided into AC power line and DC power line according to the purpose. AC power line is usually made of high voltage AC wire. This kind of wire needs unified standard to obtain safety certification before it can be formally produced. The DC line is basically through low voltage DC, so the safety requirements are not as strict as AC line, but for the sake of safety, countries still require unified safety certification.

The core section of American standard power cord is thicker than that of European standard power cord. According to P = UI (P is the power, u is the voltage, I is the current), because the working voltage of American standard power line is low, so the current passing through is greater. This is why the core section of American standard power line is thicker than that of European standard power line.

Some customers buy indoor LED display, after a period of time, the company has activities need to be used outdoors, in order to save costs, want to change the indoor LED display to outdoor LED display, is this feasible?

LED full color display power supply: the power supply is also affected by the rapid increase of LED display industry, increasing the sales of power supply. The stability and performance of the power supply determine the performance of the LED display, and the power supply of various models is also particular. The power required for LED full-color display is calculated according to the power of the unit board, and the requirements of various models are different.

If each LED string is controlled by a power supply, you can buy a high-power switching power supply as the main power supply, and then connect all the LED string input power supplies in parallel (if the wire size is not enough, it can be extended). Finally, the power supply is unified by the main switching power supply.
