4、 Coal excavator used rubber flexible cable with voltage of 1.9/3.3 kV and below shall have the bending resistant performance, it shall not cause circuit breakdown and short circuit after 9000 times bend.
Coal mine used cable has good impact, bending and press resistant performance, especially the fire resistant and flame-retardant characteristic. It also has operating secure and good earthing performance.
- Q:The computer host is always start to stop, resulting in the last can not start. What is going on?
- GB-2002 provides: metal cable bridge and its bracket and the introduction or extraction of metal cable ducts must be ground (PE) or zero (PEN) is reliable, and must meet the following requirements:
- Q:Will the computer master, external DVD burner how external power supply, please click details. Thank you!
- Regardless of multi-wire or single-core, as long as it is in line with national wire standards, and now the market is not the current market line 60% compliance. To select the regular products, national safety certification, safety standards, a good installation process and the standard of the wire, a local demand for electricity with the appropriate diameter. To ensure that you are comfortable with electricity,
- Q:Will the two 16 square copper wire with what specifications of the trunking
- How to say that interference is certainly some, if you line less words on one or two in the bridge next to do a tube it! The pipe will be a little better. Upstairs that I do not think that although in practice the construction of this practice a lot, because you do not feel the interference, but the reality does interfere with, or science should not be strong and weak must be separated.
- Q:With a i3-2100 desktop computer about how much money. To have a separate graphics card. Give a configuration alone, no more than 4000
- The length of the cable bracket is determined by how much the cable is
- Q:20 tons of double beam traffic acceptance standards and content which
- Change the data line ah, often with non-original battery will be filled with bad
- Q:The difference between the instrument cable and the low voltage power cable
- Meaning the cross-sectional area of the wire, the unit is square mm; for example: 4 square copper wire, the cross-sectional area of the wire is 4 square millimeters, copper wire;
- Q:Calculation method of wire and cable outer diameter
- Usually check the table, in the cable samples or manual check.
- Q:What is the warranty period for wire and cable?
- General cable shelf life is 10 years, look at the jacket and the insulation with or without cracks, shake the insulation resistance of the general do not breakdown can be used, but the best people to do some pressure test. The withstand voltage test must have been used.
- Q:Wire and cable manufacturing process (to be detailed)?
- Copper core per square of the safe current (continuous use) for the 2.5A, intermittent use of 4A, according to the power count 550W-880W.
- Q:Wire inside the two lines, red and black, black line is the line of fire or zero line ah?
- According to the size of the product to open a good plastic mold and then purchase the plastic raw materials to be injected (raw materials depending on your product requirements, advanced point will use To the engineering plastics PE, PS, etc, and even to join the flame retardant, fiber material), the difference is like now with the charger on the use of only PVC3 Called the wire manufacturers according to your request to do a good line Of course, you have the conditions you can pull the wire of their own beer process: mold on the machine (ingredients test mode) --- welding wire and hardware (pin) --- then put the welding hardware on the mold (according to the mold Put five to ten range) - boot molding - detection of another: If you want to have all the country's certification, it is estimated that you no technology is not too, you can not buy that hundreds of thousands of equipment to detect The power line in the material composition and a variety of techniques to wear flattened Fenbao match platinum standard, because the formal power It is too much to be recognized, but you want to do ordinary DC line, such as mobile phone charger or no problem, but the regular factory what automation machine to do, then I do not know, but it is automated machine estimates But also the cost of scary Anyway, ordinary manufacturers do have any questions can EMAIL: qingxinghe@21cncom Do not call me in Google, I rarely said so much, add points to me, huh, huh
