Pharma cold chain HS code analysis

Check whether the size of the wire meets the relevant requirements, and the model is incorrect. The incision must be neat, the wire must not be scratched, and the wire must not be dirty. Whether the grouping is neat. Check whether the trimming is neat and the size is correct. When trimming the grouping, the core line cannot be drawn.

The length of the trunk line and protective sleeve should not be less than 100mm, which is a multiple of 10. For example, 100mm, 110mm, 120mm, etc. 2 The length of the pipe should not be less than 30mm. The distance between the contact and the branch point should not be less than 20 mm.

In order to ensure a certain mechanical strength, the cross-sectional area of low-pressure conductors is generally not less than 0.5mm2.The cross-sectional area of a single car wire is 0.0.825, etc. The recommended specifications of low-voltage conductors for automobile 12V electrical system are shown in the table.

Automotive conductors are divided into two types: high-voltage wire and low-voltage wire. The main performance index of high-voltage wire is insulation performance, and its voltage resistance should be above 15,000V.

What are the models and specifications of automotive wires

1. The common specifications of automotive wiring harness electronic wires are nominally cut off: 0.0.70, 0, 0, 0 and other square millimeters of wires, the key is to look at the maximum current value of the load, and use Wires of electrical equipment of different power.

2. Driving cable model: choose YC/YCW series general-purpose rubber sheath cable for ordinary occasions. YCW is more suitable for outdoor driving.

3. Common specifications are: 3*10+1*3*16+1*3*25+1*163*35+1*23*50*13*70+1*33*95+1*50, 3*120+1*70, 3*150+1*70, 3*185* 1*93*240+1*120, etc.

How many cables does a car consist of

1. The motor input of an electric vehicle is generally three cables, and its colors are red, green and yellow respectively, because now electric vehicles generally use three-phase AC asynchronous motors, and they only need three electric The cable can be operated by outputting three fire wires.

2. Four lines. Three-phase line (fire line) is a zero wire, and the transmission line generally adopts a three-phase four-wire system. Three of the lines represent A, B and C three phases respectively, and the other is the neutral line N (if the neutral point on the power side of the loop is grounded, the neutral line is also called the zero line. The number of roots of the cable core wire is required to be 4 cores.

3. First of all, we need to understand the structure of the cable. 5*6 cable refers to 5 cables with a diameter ofIt is composed of 6 square millimeters of wires, while the 4+1*6 cable is composed of 4 wires with a diameter of 6 square millimeters and 1 additional wire. This change is mainly to meet different types of charging needs.

4. Ha ha, in fact, the theory of physics is correct. I can call a wire: one-phase electricity. If the wire on the train is a fire wire, then the steel rail is a zero wire. To put it formally, the traction power supply system mainly refers to the two major parts of the traction substation and the contact network.

5. There are many kinds of connectors, which can be used to connect several to dozens of lines, including cylinders, cuboids, cuboids and other different shapes. The plug-in of the plug-in consists of two parts, yin and yang, called socket and plug respectively.

What does avss wire mean

1. AVSS wire refers to an extremely thin automobile line cable, which is often used for wire connection of electronic equipment and instruments inside the vehicle. This kind of wire has excellent high temperature resistance, tear resistance, chemical corrosion resistance and other characteristics, which can ensure the reliability and durability of the wire in harsh environments.

2. AVSS is a Japanese standard automobile line, and UL is an American standard wire. As long as it is certified, there is an imprint on the wire. UL has a certification number and begins with the letter E. If you need wires, you can contact me.

3. The insulation thickness is different: the standard insulation thickness of AVS is 0.50~0.70mm, and the standard insulation thickness of AVSS is 0.30~0.40mm. Different properties: AVSS-thin-walled low-voltage PVC wire, AVS-low-voltage PVC wire. Different thickness: AVSS wire is an ultra-thin wall wire. AVS wire is a thin-walled wire.

4. Japanese standard automobile line. AVSS/HF is a Japanese standard automobile wire. AVSS is a PVC insulated ultra-thin wall low-voltage automobile wire. Avss wire has the advantage of light weight.

5. The difference between American standard wire, German standard wire (FLRY) and Japanese standard wire (AVSS, etc.): 1) Japanese standard AVSS (AVS) wire is characterized by thin skin insulation and good flexibility; 2) German standard wire insulation skin is thinner and good flexibility; 3) American standard wire insulation The skin is generally thermoplastic or thermosetting elastomer, and it is also processed by irradiation process.
