At present, the low-level distribution lines in a large number of residential buildings do not meet the standards set by the state. Consumers lack understanding of concealed projects such as electrical lines during home purchases and renovations, resulting in a large number of hidden safety hazards. Electrical fires and electric shocks occur at times. . At the launching ceremony of the “Advocating Scientific Consumption and Paying Attention to Home Wiring†activity that was just held by the China Consumers Association and the International Copper Association, the experts reminded consumers to ask for electricity before buying a house, and to securely install wiring during the renovation.
There is a lot of copper problems
According to an expert from the Copper Association, the country has already made it clear that copper conductors should be used in new houses. But also copper conductors, poor quality copper conductors, copper cores using recycled copper, containing many impurities, and some poor quality copper conductors even worse than the conductive properties of wire, easily lead to electrical accidents; high quality copper wire, the copper core of high purity Made of fine red copper, the outer layer is bright and slightly soft.
Insulating materials used for inferior copper conductors are recycled plastics, which have a dull color, loose texture, uneven thickness, low insulation capacity, and are prone to aging or breakdown and cause short circuits.
Some unscrupulous manufacturers often make a fuss about the length and cross section of the wire, cutting corners, length and cross section, often fail to reach the specification of the mark.
Comprehensive understanding of the copper standard
Material selection <br> If you are decorating an old house, the original aluminum wire must be replaced with copper wire. Because the aluminum wire is easily oxidized, the connector easily ignites. According to investigations, the incidence of electrical fire using the aluminum wire is several dozen times that of the copper wire. If only the switch and the socket are changed, it will bury potential safety hazards for the occupants in the future.
Conductor cross section
From the perspective of electrical safety, the national residential design specification states that the branch circuit section should be no less than 2.5 mm2. Air-conditioning and other high-power appliances are best to walk a 4mm2 line alone. If you consider that in the future the number of kitchen and bathroom appliances will increase dramatically, the circuit of the kitchen and bathroom is best to use 4mm2 copper wire.
Number of loops
Sufficient loop count is essential for modern home life. When a short circuit or other problem occurs on a line, it will not affect the normal operation of other circuits. According to the area of ​​use, lighting circuit can choose two or three way, power socket three to four way, kitchen and bathroom go all the way, air-conditioning circuit two to three roads, one air-conditioning loop with up to two air conditioners.
Wiring method
In order to be aesthetically pleasing and easy to inspect and replace, slotting and dark pipe laying are generally used. In the wiring process follows the principle of "fire line into the switch, zero line into the lamp".
Leakage protection <br>In addition to air conditioning power outlets, other power outlet circuits should be equipped with leakage protection devices.
Socket installation attaches importance to the rules
Number of outlets
The number and variety of electrical appliances in each household is increasing, and many households use pull-out socket boards to meet their electricity needs while ignoring security factors. The State Bureau of Technical Supervision conducted a random inspection of the socket board in the first quarter of 1999. The results showed that there are types of sockets near the socket to prevent children from getting an electric shock. A safety socket with a safety cover should be used; refrigerators and air conditioners should be used independently, with protective grounding. Eye sockets; bathroom is easy to wet, should not be installed ordinary sockets should use splash-proof water socket.
Installation position
Generally, the switch is 1.2-1.4 meters away from the ground, and the horizontal distance from the door frame is 0.15-0.2 meters. The height of the same room switch should be the same; the surface mounted socket should not be less than 1.8 meters from the ground, and the concealed socket should be 0.3 meters away from the ground. Of course, the specific installation location has to be determined by the placement of furniture and electrical appliances.
Installation method
Single-phase two-eye socket wiring requirements are: "zero-left-right-fire" when horizontally arranged and "lit" when arranged vertically?

Razor wire ss304 Razor Barbed Wire is a spiral( Ss Barbed Wire ), coiled up form of reinforced barbed tape. The adjoining loops of the spiral are clipped in a particular way making the concertina wire spatial and inseparable.
The core wire diameter. 2.5mm is the industry standard, anything less is likely to offer less tensile and inherent strength.
The number of loops per coil: This determines the amount of Razor wire on the coil and therefore the profile density when deployed, an important point when comparing prices. All our coils have 55 loops per coil!
Stainless Steel or Galvanised? The environment the product is being deployed in may determine whether SS or Galvanised is the best option. Stainless Steel is more expensive but offers greater durability especially in salt air environments.
Blade type. Smaller blades such as BTO10 are quite small and therefore less of a deterrent, larger blade profiles such as CBT65 are much more effective but the blade type will also be reflected in the price.
Blade thickness. 0.5mm is the industry standard, anything less is likely to bend easily.
Coil extension length. The length the coils can be extended to is determined by the number of loops and clips each type of coil has. Generally most coils extend to between 9m and 13m comfortably without compromising the profile density.
