Description
Grade 4234 is sioplas (two steps) silane XLPE compound and suitable for 1kv and below low voltage cable, it is composed by 95% silane crosslinkable low density polyethylene (compound A) and 5% catalyst (compound B). The product has outstanding performance in high speed extrusion, smooth cable surface, wild processing temperature, easy processing and convenient to use.
Standard
After crosslinked in the tepid water, the cable made from our product grade 4234 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) 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 4234.
The recommended equipment and processing technique isas 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 asfollowing:
Feeding Section（℃） | Compression Section（℃） | Measurement Section （℃） | Die head and Mould （℃） |
130~155 | 155~170 | 170~180 | 180~200 |
Die head setting: Squeezing extrusion style is recommended
Cooling water temperature: Should not beless than 25℃,gradual cooling water tank 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:What are the varieties of wire and cable (detailed point)
- Cable regardless of the definition of the number of elements in the definition of a few such as: YJV-3 * 50 + 1 * 16 calculated the number of lines is always a different, different wire rules Model input: bv-2 * 2.5 / bv-3 * 4 (different material), bv-2 * 2.5 + 3 * 4 (the same material)
- Q:The data line is my online to buy the extension of the line, has been able to use, and today suddenly can not charge the electricity, and pop up the tips, which is why? More
- What do you want to do? Do network cabling buried? Or in the building after the tube?
- 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:Apple phone display cable or accessories not certified how to do
- Indicating that your Apple data cable is not original, no effect, re-plug the general and you can use the.
- 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:I would like to ask my new workshop power consumption of about 500KW, injection molding machine, 60KW . 40KW . 20KW . the other 20KW, how much should the wire? Respectively how to use lines and switches more
- No way to save money! Moreover, the signal to you there, almost all attenuation finished.
- 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: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...........................
- About 140 PVC threading tube, which depends on how many lines you row. PPR cold / hot water pipe 42 meters, PPR cold / hot water pipe with 4 m / root and 6 m / root of the points, short will make the joints more recommended to use long, generally longer expensive. Decoration in meters to count, to facilitate the settlement of labor, 42 meters is the amount of my home My house 115 square meters, indoor area of 98 square meters. I hope useful to you. According to the 2011 price, the general brand of wires and pipes, their own materials to buy, without artificial about 4000-5000 yuan. I decorated last year, the package to the decorating company hydropower workers with me to calculate the 9800 yuan it, of course, each region has a price difference.
- Q:Apple 6 Charging Why always show this cable has not yet been certified
- Cable and cable distinction In fact, "wire" and "cable" and there is no strict boundaries
- 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,
