What is a multi-core wire? Multi-core wire refers to a conductor with two or more cores in an insulating layer, like the RVS, RVV, RVVP that we usually see are multi-core wires. Let's introduce the characteristics of multi-core wire.



First, product characteristics

Multi-core wires are generally soft, used in active power places and temporary power places, easy to install, drag and drop and move. However, after the high temperature of the multi-core wire, the surface is seriously oxidized, the effective cross-section is greatly reduced, and it is easy to break the core, local heating and other problems, if this happens, it is recommended to replace it in time from the safety of electricity.

Two, multi-core wire color

Commonly used single-core wire colors are: red, yellow, blue, green, brown, black, yellow-green.

Third, product use

Household wire single core is good or multi-core is good, and there is no fixed argument, according to the specific use to decide, like our lighting line, can all use 1.5 single strand copper core wire; 2 2P(including) more than the air conditioning, that is, hot electric water heater, bath must use 4 square double strand copper core wire; The rest of the line is an ordinary 2.5 double copper core wire.

Wire is one of the main works of home decoration hidden, without wire, the electrical appliances in the house can not run. After years of development, traditional PVC wire has gradually entered thousands of households. With the passage of time, the drawbacks of traditional PVC wire have also been exposed. After the Yangtze River waves push forward waves, fireproof wire came into being, under the leadership of fireproof wire broke out a world.

1. Short terminal life

Ordinary household wires, under normal operation, generally 12-20 years will be aging, tripping is also frequent, once short circuit, the wire is easy to melt, smoke, cause small sparks and even cause fire. Many of the houses that caught fire are relatively old residential houses, which is because the wires in the house are aging and can not stand too strong current and short circuit, which causes the fire. Fireproof wires don't have this kind of trouble.

2. End power failure

Traditional PVC wire load power is limited, and the use of a long time, overload, short circuit always appear, causing inconvenience to living, but also does not save electricity. The fire-proof wire adopts anti-aging technology, standard wire length and reasonable ratio to achieve the effect of stable resistance, no leakage and no electricity consumption for long-term use.

3. End not fire

Fireproof wire, as the name suggests, is a wire that can be fireproof to a certain extent. Chuangyuan fireproof wire adopts the patented firewall technology, which can burn for 90 minutes at a high temperature of 1000 degrees Celsius, low smoke and non-toxic, and will not emit toxic gases like traditional PVC wire. And the insulated shell of the fireproof wire can be effectively flame retardant, and the expansion of the fire can be controlled to a certain extent.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
