Description

Grade 4214N/4244N is sioplas (two steps) natural curing silane XLPE compound, it is composed by compound A and compound B.Compound A is high-quality special polyethylene material with unique grafting process, while compound B adopts the advanced catalyst system. The product can be quickly crosslinked in hot water or after some time exposed in the air, it is suitable for 3kv and below low voltage cable. The major characteristics are

◆Quick crosslinking speed, not necessary be boiled in hot water, simplify the procedure, and improve the production efficiency and cost saving.

◆Non-corrosive tothe equipment line, non-corrosive to copper conductor.

◆Less affected bythe masterbatch.

Grade 4214N is suitable for the extrusion method of squeezing extrusion,half-tubing extrusion and tubing extrusion; grade 4244N is suitable for tubing extrusion method.

Suitable for small cable with cross sectional area equal to or larger than 1.5mm².

Halogen free, and environment friendly.

Standard

Performance test is in accordance with JB/T 10437-2004standard. The cable made from the product grade 4214N/4244N can comply with the standard of IEC60502-2004, GB/T12706-2002.

Typical values were tested on the 1mm sample strip by squeezing film extrusion after mixing compound of A& B (at percentage of 95:5), double-sided exposure in the constant temperature and humidity box (23℃, relative humidity 75%) and measured after 48 hours.

*Especially, these typical values were tested on fully solidified and cured sample (If the sample is not fully cured, it will continue the curing during ageing procedure, and consequently will affect the test result before and after heat ageing).

**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 one hour.

Recommended Processing Technique

1. Extrusion Equipment

The product is easy to be plasticized, ordinary PVC-use single screw extruder (length-diameter ratio is 15 to 20) can be used,the equipment requirement is relatively simple screw structure and the flow way is smooth and no dead end.

2. Extruder processing temperature and other related settings

Temperature Setting: Specific processing temperature should be based on different equipment and pressing conditions, reference settings are asfollowing:

Grade

Compression Section（℃）

4214N

160~170

170~180

4244N

130~140

150~160

160~170

Die head setting: 4214N is suitable for squeezing extrusion style, half-tubing extrusion style and tubing extrusion style. 4244N is suitable for tubing extrusion method. To produce with tubing extrusion style, the recommended draw ratio is less than 1.2 (4214N) / 1.3(4244N), the greater the draw ratio the greater the thermal shrinkage.

Cooling water temperature: Should not be less than 25℃, gradual cooling water tank is recommended.

Conductor temperature: Appropriate warm-up the copper or aluminium conductor, which can further reduce the heat shrinkage of the insulation and accelerate the cross link speed.

Crosslink Speed

For the cable made from this material, the cross link speed has close relation tothe insulation thickness, ambient temperature, environment humidity and coilsize. The thinner and smaller the coil size, the higher temperature and humidity, the shorter the time needed for cross linking. During cold and dry winter season, the crosslink speed in natural environment will be comparatively slow down. To reduce the cross linking time, it is recommended to spray some hot water on the surface of the insulation to accelerate cross link procedure.

Insulation thickness	23℃, humidity 75%	35℃, humidity 60%	90℃ in water
0.9 mm	2-3 days	1-2 days	＜30 min
1.4 mm	5-7days	3-4 days	＜60 min
1.8 mm	8-10 days	5-7 days	＜90 min

Note:The above data were tested on the sample by squeezing film extrusion after mixing compound of A & B (at percentage of 95:5),double-sided exposure in the constant temperature and humidity box;the above value may differ from the actual cross link speed.

Q: Four lines only reached a phase line, at the other end all charged, I use the digital pen! In addition, I often check the cable when the cable current through the dot digital pen voltage symbols sometimes have time to disappear, in other bare wires when the test keys are normal! What is this going on! Ask the heroes to give the younger brother a complete point of the answer! More: Bookstore tool book should have "communication project budget", I do is what you say, the budget is divided into estimates and budget, is two steps. So that is not very clear. But what is needed is the preliminary design of the project. The budget is needed for design and drawings. Internal management of this piece, the main thing is that you need to do what the project department, and are generally very complicated

Q: What brand of cable is good, what are the top ten brands of wires?: If you are talking about the three-core wire, black - ground brown - line of blue - zero line. If it is 3 plugs, your wire is only 2 lines. Then the yellow received L, black received N. The above is the ground wire.

Q: Apple 6splus charge may not support this accessories how to do more: When the lighting circuit and the power circuit shared ladder, BV line is not allowed to put in the ladder, so it is recommended to use the wiring of the lamp ZC-YJV-3 * 2

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: Rt, the charger did not change, has been no problem before, today just plugged into the charger, the results appear as if the problem, before the out of this problem, and now only ipad power off after the power can not be charged, and ipad start , Then immediately prompted the title, can not charge more: Budget 1W5 requires the whole machine to include the display of the monitor not too big too much Not used to more

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,: Wiring room refers to the distribution of the weak floor of the room, the weak point refers to the building weak vertical pipe

Q: Wire and cable CCC product consistency is what: What brand of wire pipe PVC pipe used? Is not in the financial or plastic surgery better ah? Guiqiu we recommend, thank you! What brand of network cable used a good, need double shielded cable, thank you

Q: Apple mobile phone does not support this charge when charging this thing how to charge: Just show that the sound is still in the host, must be an external sound, your computer monitor can sound it? Not to sound - Bao Haiping studio

Q: Apple 6 Charging Why always show this cable has not yet been certified: Set-top box with the AV cable connection: yellow - video, red and white - audio, corresponding to the TV's AV input interface can be connected (do not receive the TV component interface). As for the emergence of partial pink, the possible reasons are: . poor contact. You will re-connect the three-color AV cable to the set-top box, on the TV, to ensure good contact. . cable quality. Three-color AV cable may not be the quality, if you can replace a group of try, or use the DVD and other equipment connected with the TV to test the AV line with or without problems. . TV AV input failure. You can use other video source equipment connected to the TV test, such as: DVD, VCD machines and so on. . set-top box failure. May be set-top box AV output port problems, if there are multiple sets of AV output, you can try other port okay, not the case may be the quality of set-top box, call customer service it.

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