Domestic wire is basically divided into five categories: bare wire and bare conductor products, power cables, electrical equipment with wire and cable, communication cables and optical fiber, electromagnetic wire. These five types of wires in our daily life is the most commonly used bare wires and power cables, and most of the other is used for industry and communication, then these cables need to do what what testing certification? Let's take a look at it:

1, electrical performance testing: the main conductor DC resistance, insulation resistance, finished product voltage test and insulated wire core voltage test, each is very important, conductor resistance directly reflects the electrical transmission performance of the cable, directly affects the cable in the energized operation of the temperature, life, voltage drop, and operation safety.

The insulation resistance, the finished product voltage test and the voltage test between the insulated wires are all examining the electrical insulation performance of the cable insulation layer and the sheath layer. The insulation resistance is the resistance of the insulating material between the two conductors, which should be large enough to play the role of insulation protection.

2, mechanical performance testing

It is mainly to examine the tensile strength and elongation at break of insulation and sheath plastic materials, including before and after aging, as well as the bending test, bending test, load breaking core test, insulation core tearing test, static bending test and so on for finished flexible cables.

In addition, because the flexible cable is not fixed laying, there are repeated dragging, bending and other situations in use, so the flexible cable standard also stipulates that dynamic bending test, bending test, load broken core test, insulated wire core tear test, static bending test, etc. are added to the finished cable to ensure that this cable meets the requirements in actual use.

As we all know, the low-price bidding system of the cable industry, resulting in the cable industry has to reduce the technical indicators of raw materials, procurement prices, resulting in a serious decline in product quality, the test is not passed, and the majority of colleagues in the cable industry must do "conscience cable" and sell "conscience cable".

At the same time, call on the masses to sharpen their eyes, recognize the brand, must not be greedy for the "small cheap" in front of them, buy, use fake and shoddy wire and cable. Resolutely resist the "black cable", resist the phenomenon of counterfeit and shoddy, purify the industry environment, and jointly safeguard the life and property safety of consumers.

Often, after a period of operation and maintenance of the integrated wiring system, the connection information of the line is basically in a state of confusion, and the line connection relationship can only be clarified by on-site combing.

The confusion between cables is reflected in two aspects: visual and data, and the main reason is the lack of standardized wiring methods and appropriate change recording means.

How to choose the right wire organizer, standardize the way of wire management, crack the visual chaos of wire distribution?

In the actual project, we often only configure the horizontal cable organizer, no vertical cable organizer, side cable ring, the use of unreasonable bundling method, resulting in the subsequent jumper is not easy to tidy.

Mistake 1: Tying jumpers with cable ties.

Jumpers change frequently with service changes. The cable tie is a one-time product, which is not conducive to changing the jumper, and excessive bundling will affect the cable characteristics.

The correct way is to use Velcro

Mistake 2: Configure only horizontal cable managers

Only a horizontal cable organizer is configured. No side cable ring or vertical cable organizer is configured. Jumpers must be routed horizontally and vertically. Only a horizontal cable organizer can be configured. Vertical cables cannot be properly combed. The correct way is to configure a horizontal cable organizer, vertical cable organizer, or side cable organizer.

The right way: Configure the horizontal cable organizer, vertical cable organizer or side cable ring at the same time.

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.
