In the south where there is no collective heating, the winter can only be heated by electric appliances such as air conditioners and electric oil lamps, and the pressure on the electricity is naturally large.
Especially for renters, rental outlets are often not enough plugs, so often there plug plaque full of circumstances, if there is an even more high-power electrical appliances, electricity safety does not necessarily have to promise.
What kind of plug-line only fly?
About plug-in board, in the test plus disassembly case, can indeed say a lot of doorways, but the average consumer does not have such conditions, then the first and most simple screening method is the three words: 'new National standard '.In April 2017, the new national standard patch panel formally launched, then do not meet the requirements of the new national standard products can not be produced and sold, and the market already exists in the old national standard products can only be sold until 2018.
However, a real laboratory in the East search a bit, there are still advertised 'new national standard' patch panels, cut corners on the specifications:
Did not change the 1 mm square wire with no protection door, dare to call a new national standard?
Then the 'new national standard' are provided what? The new standard mainly increases the requirements of the jack to force the addition of protective doors, while the flame retardant properties also have more stringent requirements.
Security door jack is already standard
In addition, the new GB and the most obvious difference between the old standard is the wire requirements, the rated current of 10A extension cord (1.8 meters below) socket, the minimum cross-sectional area of the wire from the original 0.75 square millimeter to 1 square Mm; nominal 16A increased from 1 mm2 to 1.5 mm2.
Can be seen that the new national standard to improve the safety of the socket and carrying capacity to reduce children's misunderstanding of the socket and due to overload caused by the cable security incidents.Therefore, see above the old standard patch panel, do not be virtual standard Fool it.
0.75 and 1 difference far?
In terms of safety, 0.75 mm2 and 1 mm2 wire is really far worse.We first look at a set of data:
According to the actual measured data show that the high load (3,400 W) working conditions for 1 hour, the use of cross-sectional area of 1 square millimeter wire GB board, the power cord temperature than the old standard plug-board lower by 19 ℃, if Power to further improve the old standard patch cord wire is likely to melt or even short-circuit smoke situation.
Light from the security point of view, the new national standard plug-in board will be much better than the old section too. New Year approaching, do not forget to go home to buy a new national standard patch panel, send a safe to the elderly! Listen Up is not like the New Year TV ads? However, I often see the elderly at home to buy cheaper plans to buy some have not heard of the brand plug-in boards, and even have a million, small universal patch panels that have long been eliminated The type, it is really worrying.
Especially in summer and winter peak season of power consumption, the use of high-power electrical appliances is still quite frequent, except when choosing high-power electrical appliances to be careful, with the work of the plug-in board can not be sloppy, if everyone at home have years of service Old patch panels, then, may wish to consider the new national standard products.
