Description

Grade 4244Q is sioplas (two steps) silane XLPEcompound for low voltage cable with small cross sectional area, it is composedby silane crosslinkable low density polyethylene (compound A) and silane crosslinkable catalyst (compound B). Compound A is grafted by high activity silane and special PE compound, while compound B adopts the advanced cataly stsystem. The product has outstanding performance and major characteristics are

◆The product is suitable for the extrusion method of tubing extrusion.

◆Cables made from the product have excellent performance in smooth cable surface, high extrusion speed and production efficiency.

◆Suitable for cable cross-sectional area less than 16mm².

◆Low processing temperature and cost saving.

Standard

Performance test is in accordance with JB/T 10437-2004 standard. After crosslinked in the tepid water, the cable made from the product grade 4244Q 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 4244Q.

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

Feeding section（℃）

Compression Section（℃）

Measurement Section

（℃）

Die head and Mould

（℃）

130~150

150~165

165~175

175~195

Die head setting: Tubing extrusion style

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℃.

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?: 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 6splus charge may not support this accessories how to do more: Sometimes no way, the problem to the owners to solve the common, must wear, the owners agreed

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....: According to the "Power Engineering Cable Design Code" GB-. 5.3.3 only asked for the depth of the cable buried directly: drop the blue skin to the ground depth, not less than 0.7 meters; when located in the roadway or farmland Under the appropriate should be deepened, and should not be less than 1.0 meters. 5.4.3 protected pipe buried in the ground, should meet the requirements under the depth of the pressure and environmental corrosion resistance. Through the uneven settlement of the backfill section and other places to increase the force, it is appropriate to use steel. Another direct burial should be selected armor type.

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: The second floor of the formula is correct, my space also have this formula, with armor and no armor in the current no difference, there are differences in the installation, usually buried to armor, overhead or bridge without armor, you give the model is not Armor, YJV-4 * 240 without armor, YJV-22-4 * 240 armor,

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: Cable is a unified call, including power cables, communication cables, etc., I do not know what type of cable you need the type specifications. On the power cable in terms of the main models are: VV, BJV, VV. BJV. . ZR, NH and other models, as the specifications that too much.

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: What are the varieties of wire and cable (detailed point): (The difference between the two cables: WDZ and WDZC are the combustion characteristics of the cable, both halogen-free low smoke flame retardant cable, but the former is a single vertical flame retardant test, which is bundled combustion C class flame retardant Test, but the flame retardant performance requirements are not the same. The meaning of the letter: W refers to the halogen-free; D refers to the low smoke; Z refers to the flame retardant WDZ is halogen-free low smoke flame retardant jacket power cable. WDZC refers to halogen-free low smoke C-class flame retardant reference )

Q: This cable or accessory has not been certified and may not be able to work with this iphone reliably: The operation of the hydraulic pipe is very simple to see it will engage in their own, embedded more simple, and then get the construction site in accordance with the requirements of the drawings put away, tied with tie wire on the OK Mouth up the pipe to use cement bag to prevent good, to prevent the infusion of concrete, so buried even if the end

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...............
