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.

Main Properties & Typical Values

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:Apple 6splus charge may not support this accessories how to do more: When the lighting circuit and the power circuit shared ladder, BV line is not allowed to put in the ladder, so it is recommended to use the wiring of the lamp ZC-YJV-3 * 2

Q:Wire and cable fire resistance to meet what standards, which can provide about, thank you!: Replaced with 30 * 30 PVC flameproof trough, side wiring side cover.

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: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: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 is the difference between "wire" and "cable"?: Inkjet printer is not printed, pictorial machine high definition, generally used in the advertising industry, for large outdoor advertising, the nozzle can choose not necessarily the number of installed, the more spray, spray the faster, a nozzle of the general life 1 year.

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: According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.

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 is the difference between the WDZ wire and cable, the ZR wire cable and the NH wire and cable, and what kind of wire and cable should be used?: BV1 * 2.5 is a 2.5 square line. 2 * 2.5 is two 2.5 square lines. 3 * 2.5 is three 2.5 square lines. 4 * 2.5 is the 4 2.5 square line lighting wire power cord with 2 * 2.5. Light wire with 1.5 is enough. Socket (pipe) with three 2.5 square lines, you can also use 3 * 2.5 a. 4 * 2.5 for three-phase motors.

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.
