insulation resistance

When the length of the cable is 100M, room temperature is 20℃,  shake test for 1 minutes with 1000VDC between the shielding layer and the conductive wire core, the minimum value of insulation resistance should be20MΩ.

working voltage

220, 380, 600 volts, AC and DC, low voltage products shall not be used in high voltage condition.



Installation method

 

1. The selection and installation of the power cable, Use copper wire, cross-sectional area≥1.5cm2. It’s better to choose low smoke and non halogen wire. The connection wire of power cable should be divided into the following color :


1, Phase - the same as the power color


2, N line - Blue insulated wire


3, PE line - Interphase as green and yellow insulated wire



Joint method of power cable and heating cable

 

Firstly deal with heating cable conductor leader insulation. Then deal with the power and heating cable conductor joint according to the electrical wiring rules.


The end blocking method of the heating cable

 

1, Firstly, cut the end, separate the end and the conductor, attention: The end of two conductors is strictly prohibit articulated.


2, Using high-pressure self-adhesive tape wrapped end to 2cm, then wrapping one more layer with PVC waterproof tape, prevent high-pressure self-adhesive tape shedding and aging.

Q:What are the requirements for the construction of electrical wiring
Office with galvanized pipe, is the kind of iron, tooling should galvanized pipe, fire! Home can have, but galvanized are more expensive, so home improvement is less use!
Q:How does the cable shield be handled as qualified?
If the fiber is broken and no damage, tighten the sheath to dismiss, I think the original set should be no problem. If there is no way to damage the key, and must be re-head, use a dedicated equipment to burn. I've seen someone else done it. Generally engaged in radio and television communications company, the equipment.
Q:Types, specifications and types of marine wire and cable
2: excellent anti-aging, can be used for a long time outdoors
Q:Cable YJV-VV-4 * 240 + 1 * 120 / 1KV What does it mean?
In the GB-96 "thermal power plant and substation design fire safety regulations" Article 9
Q:Trouble everyone to see, I like this computer configuration is good or bad!
For the signal cable, shielding is only one aspect, not the most important side, the power cable is shielded, the key is the concept of twist: "the two insulated copper wire at a certain density twisted together, each wire The radio waves radiated in the transmission will also be offset by the waves emitted by another line. "Therefore, the transmission of many differential signals, the use of signal cables is necessary, and the actual analog signal transmission is more dependent on shielding, rather than twisting , For the analog signal using the total shielding plus single-shielded cable specification is also no clear requirements must be used (except for intrinsically safe grounding) View the original title & gt;
Q:Low smoke halogen-free flame retardant wire and cable material, can do with the production of PVC screw ah?
Or other operational errors or malfunctions Or you can call digital TV customer service phone, so that they check the set-top box Or your TV only one av, av2 is av output or in fact is the color interface For reference only, do not look at the instructions Or reliable professional technicians who contact TV repair, or warranty
Q:What is a structured cabling system? Which subsystems can it be divided into?
white tie looks clean and tidy So in the communication equipment and cable using white cable is more Using UL approved nylon-66 (Nylon66) made of injection molding materials, fire rating 94V- acid, corrosion, good insulation, not aging, strong endurance The operating temperature is minus 40 to 90 degrees The product has a fast banding, good insulation, self-locking ban, easy to use and so on Plastic tape because of the specificity of the product (thin wall, the product injection process is relatively large), the mold, injection molding process and materials are very particular about the general new manufacturers need a long process to produce qualified products Cable products with a fast banding, good insulation, self-locking fastening, easy to use and so on Can be applied to the electronics factory, bundled TV, computer and other internal cable, lighting, electrical, electronic toys and other products within the line of fixed, mechanical equipment, oil pipeline fixed, the ship on the cable line fixed, bicycle packaging or bundled Other objects can also be used for agricultural, gardening, handicrafts and other bundled items Ties are widely used in Christmas gift factories, electronics factories, wire processing plants, wire and cable, toy factory, festive festivals, stationery department stores, fresh supermarkets, residential daily, electrical appliances, connectors and other items bundled
Q:Why E-Mat (E-5A-4) is used in the energy industry (nuclear power, petrochemical industry) emergency circuit, cable tray
1. On the software itself: By default, the Windows XP system retains 20% of the system bandwidth for security and stability. For the average individual users, this is obviously some conservative, wasted valuable network bandwidth. So how to recover this part of the resources? The bandwidth is the difference between the highest frequency and the lowest frequency that the communication signal can use. We know: the wider the road, the unit time can pass the traffic flow is greater. If the transmission rate of the network signal is compared to traffic flow, the bandwidth is equivalent to the width of the road. Therefore, modify the original WindowsXP system settings, fully tap out the 20% of the bandwidth potential, will be able to maximize the Internet speed. Modify the WindowsXP system This setting is as follows: 1. Click Start → Run, type: gpedit.msc, and click [OK] button, you can see the "Group Policy" window. 2. In the "Computer Configuration" project, click Start: Administrative Template - Network - QoS Packet Scheduler; and then on the right side of the window, find "limit to retain bandwidth" one, right click on the item; Click on the "Properties" menu, you will see the "limit can retain the bandwidth properties" window. 3. In the "Settings" tab we can see: WindowsXP system default "bandwidth limit" value is 20%. Change it to 0 or 5% and other small numbers, click the "enabled" radio button; and then click the "OK" button to the new settings into the computer. After completing the above three steps, restart the computer, then try the Internet. Now your bandwidth is really used for you! Second, the computer hardware on the better CPU, graphics card; large memory, network cable can be the general point of the three external to a stable network environment (this is the network operator to solve, but more critical)
Q:How big is the installation of the trough? Can you be next to the ceiling? There is to go four lines to how much trunking?
Generally do not put the same line of the tube, the impact is: there are disturbed, there is the line aging faster
Q:[Help] brake wire can be changed to half line alignment
10 floor things are positive solution, I was using, X treasure to find a local seller, like a 4 yuan a. If the line before and after the line across the board feel will be worse, with this change will be improved.
