Description

Grade 4255G is silane XLPE compound with monosil method (one step), it is specially used for 10kv below aerial hanging power cable, it is composed by selected PE resin, gray anti-ageing masterbatch and other additives. The product’s major characteristics are

◆Outstanding anti-ageing property

◆Outstanding electrical property

◆Simple processing technique

Standard

After crosslinked in the tepid water, the cable made from the product grade 4255G can comply with the standard of IEC60502-2004, GB/T14049-2008

Typical values were tested onthe 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 (A and B mixed at percentage of 90:10), 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 4255G

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

（℃）

140~155

155~175

175~195

195~205

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 and the 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: 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: What machinery is required to make wire and cable?: Line pipe is poured before the concrete is laid on the cloth, fixed on the template or steel, pouring a need to install a class at any time to adjust its position!

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: 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,: Data line pregnant, I also appeared once for a data line on it.

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: Megohmmeter, such as measuring insulation normal, that is, induction power, the other line after grounding, the pen measured no electricity.

Q: Wire and cable: RVFV. : RVFSV. : UTP-CAT5E. : SYV-F-75-5 : RVFSP. : RVSP. : RVFVSP. What is the type of wire? Solve! More: Wipe with water that day. You can also use ink thinner

Q: Decoration when the purchase of water pipes, wires and other items included in the account: A lot of ways ah! You look at the back of the set-top box, a total of three kinds of interfaces, namely, HDMI digital signal (while transmitting audio and video signals), red and yellow and yellow chicken complex habit of glycosylation moxibustion slim faint handle (red is the right channel, white Is the left channel, the yellow is the video), the color difference signal (red, green and blue, only transmission video), S terminal (single hole four pin, only transmission video). You just put the video to the TV, the audio to the amplifier on the line. . if your amplifier does not have HDMI interface, then put the set-top box HDMI connected to the TV, the set-top box red and white two terminals, connected to the amplifier red and white input terminal, and adjust the amplifier to the appropriate channel The . if your amplifier has HDMI interface, then through the HDMI series on the line, the first amplifier or the first TV will do. . TV set after a lot of them, there is a group of AVOUT output interface, this group of red and white terminals connected to the power amplifier is also OK.

Q: IPhone6 This cable or accessories have not been certified how to solve: Labor costs you can and workers to discuss, and some labor costs are calculated in accordance with square meters, and some are calculated in accordance with the day, the specific or ask the local construction team

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: Why does the bird stand on the wire without anything, but if people touch it,: National standard line, no problem. Do not pick up the heater in winter. If not the national standard line, that copper is not easy to go wrong, then use, from time to time touch the line is not hot, there is no problem.
