Description

Grade 4251/4251B is silane XLPE compound with monosil method (one step) and is specially used for 1KV and below cable & wire. It has outstanding performance in processing temperature, easy processing characteristics and excellent product properties.

Standard

After crosslinked in the tepid water, the cable made from our product grade 4251/4251B can comply with the standard of IEC60502-2004,GB/T12706-2002.

Typical values were tested on the 1mm sample strip by squeezing film extrusion 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 4251/4251B

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 be based on different equipment and pressing conditions, reference settings are as following:

Feeding Section(℃)

Compression Section(℃)

Measurement Section

(℃)

Die head and Mould

(℃)

150~165

165~180

180~200

200~210




Die head setting:
Tubing extrusion style is recommended

   

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℃.

Please contact our customer service for more technical service.

Note:

1. The independent small package in product grade 4215B is black masterbatch, it must be mixed evenly with silane XLPE compound of monosil method firstly before use.

2. If the cables made from our product grade 4251/4251B fail in heat elongation test, it would be related to the processing techniques. Please contact us any time if you find this problem.


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: 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 itself on the anti-corrosion, no need to do anti-corrosion treatment.
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
The proportion of the cross-sectional area of the cable through the embedded pipe is 20%
Q: Do not know why not mislead. The The The The The Fire resistance is IECGBBS6387. GB is the general principle of flame retardant and fire resistant wire and cable, quoted the above criteria...........................
I think it is possible, because in our (old) substation, the cable trench is the drain, the cable erected in the cable bracket.
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: 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
casing filled with dry cement, and with a wooden hammer tamping, but a certain idea of security, high pressure line once rammed the skin is too dangerous, should be done before power, you now estimated to have power,
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: Why does the bird stand on the wire without anything, but if people touch it,
Please provide air-conditioned three-leg socket photo, because you said "open inside is 2.5 square line ~ is a separate line ~" is not very understanding.
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.
Q: Wire and cable fire resistance to meet what standards, which can provide about, thank you!
Do not know why not mislead. The The The The The Fire resistance is IECGBBS6387. GB is the general principle of flame retardant and fire resistant wire and cable, quoted the above criteria...............
