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 voltagecable. 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 to the equipment line, non-corrosive to copper conductor.

◆Less affected by the 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 than1.5mm².

Halogen free, and environment friendly.

Standard

Performance test is in accordance with JB/T 10437-2004 standard. 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 wayis 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 as following:

Grade

Compression Section（℃）

Die head and Mould

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 somehot 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:What brand of cable is good, what are the top ten brands of wires?: Mainly to distinguish the ground which is the ground, the color of the ground is generally yellow-green; wire two is the fire line L and zero line N, no ground wire, look at the plug on the LN mark, the corresponding good.

Q:This cable or accessory has not been certified and may not be able to work with this iphone reliably: Multi-core cable should be cable number, if not, should first use the table to find and put on the line with the tube.

Q:Wire and cable: RVFV. : RVFSV. : UTP-CAT5E. : SYV-F-75-5 : RVFSP. : RVSP. : RVFVSP. What is the type of wire? Solve! More: If you need an unqualified wire, you can contact this part

Q:Decoration when the purchase of water pipes, wires and other items included in the account: Outdoor fire line must use fire-resistant KVV cable, wear pipe protection.

Q:How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more: Can not be removed, and so on after the first line of fluoride, and then demolition of air conditioning.

Q:Wire and cable CCC product consistency is what: Wire of course, is to use a good slightly, the first life, ah, can not buy cheap because of cheap, like China's top ten brands to buy the brand on the purchase of these brands I feel very good ah, Po Sheng , Luneng Taishan, Far East, Shenghua cable, on the up, prosperous photoelectric, Nexans Nexans these brands of wire is still very good. The landlord you can go to the above to learn more detailed information ah, the top ten wire brand is very detailed, the landlord can understand very clearly, the above brand is very good, my father last time to go above to see, and then buy

Q:Engineering materials inspection, all types of cable wires should be issued a test report?: This approach is a lot of the general is to extend the city line, that is, line 220V AC line lengthened, some in Taobao. 2. to extend the low-voltage line, engage in a power plug on the plug, the same set of seats, you can easily do an extension line, when you want to use, docking about it, when you can not close up. This is also on Taobao, when to buy, pay attention to the socket, plug the model to the on.

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: There are [the top of the machine can be broken off the ball can be hit by Jiu turtle snow box video output cable and DVD video output line] into a junction box, and then through the sub-box toggle switch to select the 'set-top box' or 'DVD'; This junction box outputs a wire connection device or is connected to a TV.

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: At the same time, security monitoring line itself is a weak line

Q:Ipad not charge how the matter. Said the cable or accessories have not been certified, and may not be able to cooperate with this ipad reliable work....: Several sets of cables in the same height of the laying, the adjacent cable between the bridge should be considered maintenance, maintenance needs, generally not less than 0.6m. This is just a matter of theory, it does not matter. Anyway, the actual construction is to do so,
