Description

Grade 4244Q is sioplas (two steps) silane XLPEcompound for low voltage cable with small cross sectional area, it is composedby silane crosslinkable low density polyethylene (compound A) and silane crosslinkable catalyst (compound B). Compound A is grafted by high activity silane and special PE compound, while compound B adopts the advanced cataly stsystem. The product has outstanding performance and major characteristics are

◆The product is suitable for the extrusion method of tubing extrusion.

◆Cables made from the product have excellent performance in smooth cable surface, high extrusion speed and production efficiency.

◆Suitable for cable cross-sectional area less than 16mm².

◆Low processing temperature and cost saving.

Standard

Performance test is in accordance with JB/T 10437-2004 standard. After crosslinked in the tepid water, the cable made from the product grade 4244Q can comply with the standard of IEC60502-2004, GB/T12706-2002.

Main Properties & Typical Values

Typical values were tested on the 1mm sample strip by squeezing film extrusion after mixing compound of A& B (at percentage of 95:5) and be boiled in hot water at 90℃ for four hours.

*Especially, these typical values were tested by press moulding sample under the condition of 180±2 ℃, 15min, and pressure over 15Mpa, then boiled in 90℃ water for four hours.

Recommended Processing Technique

1. Extrusion Equipment

Most extruders for PVC and PE suit for 4244Q.

The recommended equipment and processing technique is as following.

Ratio of length and diameter 18—25:1

Diameter 45—120mm

Ratio of compressing 1.5—3.5

Ratio of elongation 1:1.0—1:1.5

Filtering mesh 40/60/40

2. Extruder processing temperature and other related settings

Temperature Setting: Specific processing temperature should bebased on different equipment and pressing conditions, reference settings are as following:

Feeding section（℃）

Compression Section（℃）

Measurement Section

（℃）

Die head and Mould

（℃）

130~150

150~165

165~175

175~195

Die head setting: Tubing extrusion style

3. Crosslink

After extrusion and cooling, the cable can be crosslinked by immersed in hot water (90℃) or exposed in low pressure vapour. The time required for crosslink is based on the thickness of the insulation and the coil size, the thicker the insulation andthe greater the coil size, the longer the crosslink time required. The crosslink time can be calculated according to the equation of 4hr/mm for 90℃.

Q: What machinery is required to make wire and cable?: Pouring concrete when you can line? Do you clear the problem?

Q: IPadmini. The latest version 7.1.1 up in the morning to see the non-stop display this cable is not certified does not support this feature. The The Charger original. Not on the computer charge. The Ask God to answer more: Data line problem, it may be the data line to the bad, caused by poor contact. For the sake of the root

Q: Remove the computer and wash it off. What the motherboard did not move it, that is, the dust of those dust sasses, as well as the other wire of the skin what Sassafras wash, but the computer re-connected to the Internet when the old mistakes . and the lower right corner of the red Fork appears, disappeared after the emergence. The The Said the network cable is not plugged in, but the MODERN that POWER, LINK, LINE, 3 lights are normal display. The The This is how the matter, and just also appeared keyboard and mouse just start the machine can also be used normally, but in a moment to fall, and then plug their plug re-plug the mouse lights can be displayed, but the lights on the keyboard simply do not Bright, restart the computer but good, what is going on? bother. The The I hope the master quickly to help me, and this machine is relatively old ah No problem added: on a machine, just tried to re-create a connection in the network neighborhood, useless more: Galvanized pipe itself with anti-corrosion coating, you can not do anti-corrosion.

Q: What is the difference between wires and cables?: The introduction of the device in the form of: sealing ring (sealing ring is to achieve the required protection level of the shell and the use of cash-saving brush to help find the silent material or elastic material parts) type of introduction device; casting solidified packing seal Type introduction device; metal seal ring introduction device

Q: IPhone mobile phone data cable can not charge the power, the above shows the cable or accessories not certified can not work with the iPhone,: You are not very clear: how to start again? 300μF capacitor is normal? If the sound is normal (very small) after no-load start, the cable and the motor temperature are normal, the coil can be judged to be normal

Q: Cable a fire line power and why the other did not pick up the line with a pen test also have electricity? Answer detailed point: Cable is a unified call, including power cables, communication cables, etc., I do not know what type of cable you need the type specifications. On the power cable in terms of the main models are: VV, BJV, VV. BJV. . ZR, NH and other models, as the specifications that too much.

Q: IPhone6 This cable or accessories have not been certified how to solve: The color is easy to distinguish. General yellow on behalf of the video line, red white plug left and right audio.

Q: Wire and cable model ZD what does it mean: Wire pipe water problem: In fact, this problem is very serious, then this line should be scrapped or replaced, if you continue to reluctantly use not only to bring you the safety of trouble and the insulation of the wire dropped sharply! Because there is water it will lead to internal leakage can also make the wire heat caused by wire burning and trivial trivial accident, so be sure to take the necessary replacement! Supplement: the wire out of all, with the wire to grab the absorbent gauze and the like back to the twitching, many times for the gauze to dry the water, hair dryer toward the tube to heat the tube to dry and then re-layout of the new line.

Q: Why this cable has not yet been certified: The manufacture of wire and cable is completely different from that of most electromechanical products

Q: If you want to sell wire and cable, then what to do in advance to detect? The The The The The: Line width, and can not pass the gap between the chip pins, even after, but also because the distance between the wire and the lead is less than the electrical rules specified in the safe distance. In general, the ground can not pass through the gap between the chip pins, go outside or take the gap between the two columns through the gap. The width of the ground wire can also be set appropriately, and the wire is widened by adding a polygon brass cut. The safety distance in the electrical rules defaults to 10 mils, which is relatively small, and the safety distance of the different networks should be set separately as needed.
