In the field of home improvement in the context of fine decoration policy, how to balance the high cost of high-end decoration and the limited budget of customers, how to simplify the decoration while ensuring the quality of the project, has become a problem in front of us. Qingdao Tianxing cable manufacturers remind us that the key is how to save costs at the same time, to ensure the quality of home wiring.

Home improvement wires are small and hidden, but their late use time is long, replacement is difficult, and security risks are large, so the quality must be selected well, and the price must be moderate. Qingdao Tianxing cable manufacturers recommend from 5 aspects to choose home wiring.

01 Look at the brand

Does wire brand matter? In fact, I want to say important, "don't want to be a general soldier is not a good soldier", do brand wire and cable manufacturers will definitely pay more attention to the quality of the product, in product development and technology investment will be more. The quality of home wiring will also be more guaranteed!

02 See the product

① Look at the color of the copper wire: the copper core color of the good wire is generally purple, the luster is very good, and the feel is soft. Poor wire copper core is purple black, yellow or white.

② Look at the insulation rubber: the bad wire insulation layer looks very thick, it is made of recycled plastic, you squeeze it hard, the extrusion will appear white, there will be powder fall down.

③ Look at the length of the wire: general home improvement wires are sold by the volume, a roll of 100 meters. General home improvement wire length error can not exceed 2%, section line diameter gap can not exceed 0.02%.

03 Look at the quality

① Flexibility: Copper wire has good flexibility, bending freely, and anti-fatigue effect, aluminum wire may be broken when bending accidentally, relatively hard.

Stability: Aluminum wire is easier to oxidize, and then the resistance will become larger, the load of the wire will naturally reduce, easy to cause accidents, very unsafe. Copper core stability is very good, suitable for selection.

04 Look at the packaging

See if there is a certificate on the package, and there should be specifications, dimensions, rated voltage, length, date, factory name, factory address and other information on the certificate. See if there is a national compulsory product certification "3C" and production license number; See if there is a quality system certificate; See if the certificate meets the standard.

05 See use

Copper wire and aluminum wire their cross-sectional area is the same, but the copper wire load power is larger than the aluminum wire. For example: both wires are 2.5 square lines, aluminum wire can load 2,500 watts, copper wire can load 3,000 watts. For safety reasons, it is recommended to use copper wire.

Commonly used home decoration wire model specifications are:

BV wire: It is a single-core single-strand hard wire, generally used for fixed occasions, and is a commonly used model in home wiring. It is often used to walk in a straight line through walls.

BVR wire: belongs to a single core multi-strand flexible wire, composed of 7 or more copper wire, because the line is soft, generally used in active power places, installation and construction is more convenient, often used in the corner bend line.

BVVB line: It is a flat sheathed line, composed of 2/3 BV lines, which is mostly used for decoration open line.

RVV wire: a soft-sheathed wire, consisting of 2/3 or more flexible wires, mostly used for power lines in wires, instrumentation devices.

Home improvement wire commonly used specifications are 1.5 square, 2.5 square and 4 square three specifications, 6 square and 10 square for the main line.

Lighting line with 1.5 square wire; The connector of the socket is usually BVR2.5 square wire; Wall-hanging air conditioners generally use BVR2.5 square wires; Water heaters and air conditioners use BVR4 square lines; Access line, air conditioning can be used 6 square BVR wire; The home bus is available with 10 square BVR wires.

In short, a word is: home improvement wire to choose good quality, in order to avoid "overuse" but also according to the need to choose the right home improvement wire specifications.
