Baoding copper core wire specifications and models

Wire and cable products are widely used electrical products and are indispensable production materials for all walks of life
The quality of products involving personal and property safety has a great impact on the national economy and are national production license
products. If the quality of wire and cable products is not up to standard, it may endanger personal safety or cause fire
accidents.
At present, the quality of wires in the building materials market is uneven, and the quality of some wires does not meet national standards
and is considered shoddy. If consumers want to buy qualified products, they must learn to identify the quality of wires or go to a testing agency to inspect the products.
For this reason, relevant personnel from the quality supervision department remind consumers to
pay attention to the following aspects when purchasing wire and cable products:
. Markings on the surface of wires. When purchasing, be sure to check whether there are certification marks, model specifications, rated voltage, length, manufacturing date, certification number, inspection, execution standards, factory name, factory address, etc. on the surface of the wire and the certificate. Is the label clear? At the same time, attention should be paid to whether the manufacturer's name,
product model, and rated voltage indicated on the certificate are consistent with the printed marks on the surface of the wire to prevent counterfeit products.
.Wire appearance. When purchasing wires, consumers should pay attention to whether the appearance of the wires is smooth and flat, whether there are any damage signs on the insulation and sheath layers, whether the printed marks are clear, and whether there is a greasy feeling when touching the wires. From the cross-section of the wire, the thickness of the insulation or sheath should be uniform over the entire circumference of the wire and should not be eccentric. The insulation or sheath should have a certain thickness.
.Wire conductors. Consumers should check the conductors when purchasing electrical wires. The conductor must have a certain luster and moderate flexibility. The conductor structure size must comply with national standards. Pay attention to whether the conductor wire diameter is consistent with the cross-section indicated on the certificate. If the conductor cross-section is too small, it will easily cause the wire to heat up and cause a short circuit. It is recommended that household lighting circuits use wires with specifications of . square millimeter and above for air conditioners, microwave ovens, etc.
Larger household appliances should use copper core wires with specifications of .square millimeter and above. Under the same cross-section conditions, the carrying capacity of copper core wires is one larger than that of aluminum core wires.
.Pay attention to packaging. When purchasing, pay attention to the packaging, which should be beautifully printed and complete with clear model specifications, factory name, factory address, etc.
.Check the length. When purchasing, do not buy wires without length markings for cheap prices
The length error of qualified wires should be less than .
.Scope of use. Some consumers have insufficient understanding of their own electrical appliance usage requirements and environmental conditions
and insufficient understanding of the use range, requirements, and performance of wire and cable models, and often choose the wrong model, resulting in
shortened service life and even accidents. In some places, such as entertainment venues and crowded places, the installation of general wires and cables without firefighting functions poses great safety risks.
