Note one: The wire must use copper wire cross-section
There have been investigations showing that the incidence of electrical fires in residential buildings using aluminum wire is several-tenths of that of copper wires, so copper core wires should be replaced in time in old houses. The cross section of the conductor is also clearly specified in the national residential design code: the branch circuit should not be less than 2.5 square centimeters in cross section; high-power electrical appliances such as air conditioners should have a separate circuit with a cross section of not less than 4 cm2.
Note two: At least four loops of leakage protection can not be ignored
According to the area of ​​use of the room, the lighting circuit can choose 2-3 circuits, the power socket also selects 2-3 circuits, the kitchen and the bathroom go all the way, the air conditioning can use a circuit, 4 kinds of circuits must have! It is worth noting that In the process of home decoration wiring, the principle of “fire line enter switch, zero line enter lamp cap†should be followed, and a leakage protection device should be set on the power socket.
Note three: Install enough sockets to avoid random wire pull
According to experts, if an unqualified patch panel is used indoors, electrical shock and electrical fire can easily occur. Therefore, setting a sufficient number of outlets during the renovation can avoid the trouble of pulling wires. Experts suggest that it is best to install 4 sets of sockets in the bedroom, a group of 2.5 square meters in the living room, a kitchen of 1.2 square meters, and air conditioners, exhaust fans, washing machines, etc. should use special sockets.
Note four: to the formal market, manufacturers buy wire
The quality of the conductors is related to the safety of the entire electrical wiring. The insulators used in some inferior conductors are recycled plastics, which are dull in color, loose in texture, poor in insulation, prone to aging or breakdown by voltage, and cause short circuits and fires. Some of the copper in the copper core contains impurities, and the conductivity is not as good as that of the iron wire, which easily causes electrical accidents.
Thermally Inactive Reflective Liner material is a 3layer co-ertruded Geomembrane. The product core and inferior layer remain black which doesn`t affect any technical properties of the liner. By changing the composition of the superior layer the addition of a pure white pigment composed of UV additives, Tianhai created a product that offers additional on-site benefits suitable for various applications.
Features:
Geomembranes were created to contain solids and fluids for very long periods. As such, they need to have high endurance properties. One of the best additives for plastics to resist to UV degradation is carbon black. However, this results in having black geomembrane. Black geomembrane will get very hot when exposed to sunlight because of its high expansion/contraction coefficient.
Tianhai innovated in developing a new reflective geomembrane. While having obvious aesthetic advantages, the reflective liner will also reflect the sunlight and reduce the temperature of the geomembrane. This reduction in temperature will reduce the expansion/contraction of the geomembrane which will allow for an easier installation and reduce wrinkles in the liner. For composite liner systems, reducing the wrinkles will increase the intimate contact between the liner and the low permeability sub layer which will lead to a more efficient impermeable system. It will also slow down the aging process and increase its service life.
Another advantage of the reflective geomembrane is the contrast between the white surface layer and the black core of the liner. This allows easy identification of visual defects as they will be more apparent than on traditional black geomembranes.
While reflective geomembranes seem to only offer aesthetical advantages, as expressed above, significant benefits result from using reflective geomembrane over traditional black geomembrane.
