Description

Grade 4214Q is sioplas (two steps) silane XLPEcompound for low voltage cable with small cross sectional area, it is composed by 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 squeezing extrusion,half-tubing extrusion and 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.

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 4214Q 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 4214Q.

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

(℃)

150~165

165~175

175~190

190~200


Die head setting:
Squeezing extrusion style, half-tubing extrusion style and tubing extrusion style

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 canbe calculated according to the equation of 4hr/mm for 90℃.

Q:Now the market professional installation monitoring the construction team how much money a point? , As well as cable patch panels and telephone patch panels how much money a point? Is it distance?
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: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:Where should the inner diameter of the plastic tube of the cable be at least the number of times the outer diameter of the cable?
Data line pregnant, I also appeared once for a data line on it.
Q:How are various wire and cable models named?
Cable type a lot, here to give an example: ZRC-YJV22-0.6 / 1KV3 * 25 +2 * 16 This model specification means: C-class flame retardant (ZRC) XLPE insulated (YJ) PVC jacket 22) steel tape armor (0.6 / 1KV) 0.6 / 1 kV (3 * 25) 3 25 square (+ 1 * 16) plus two 16 square copper conductor flame retardant copper core steel tape armored cross-linked poly Ethylene insulated PVC sheathed low voltage electric power.
Q:Help look at such a configuration will not have compatibility issues! Do you need to improve? Budget in 5500 or so
This situation generally have to extend the line triangle can link the ground, the two feet when you use the foot to feel the foot, and step on the bench as long as the non-conductive feel. No seriousness
Q:What is the difference between wires and cables?
The introduction of the device is to introduce the cable into the electrical equipment, without changing the explosion-proof type of explosion-proof equipment
Q:What is the difference between a kbg threading pipe and a PVC threading pipe?
The expression is not very clear, it should be said to wear a tube, if a single wear on the line 100. Outside diameter 60mm.
Q:What is the cable for rvv? Is it a power cable or a control cable? What is the cable?
The installation process is a certain requirement, high and low voltage cable bridge should be installed separately as usual, a wall laying vertical pipeline (slot) or installation equipment, the power distribution between the depth of D1 = 1200 ~ 1500mm; weak Between the deep distance from the D2 = 1100 ~ 1400mm more reasonable. The length L1 and L2 between the power distribution and the weak can be determined according to how much electrical equipment and pipelines (slots) are installed in the room. "Civil building electrical design specifications" proposed "shaft size in addition to meet the wiring spacing and terminal box, distribution box layout must be the size, but also in the box before the left not less than 0.8m operation, maintenance distance" requirements. In the weak equipment, the operation and maintenance distance is not specified in the provisions of the Code for Electrical Design of Civil Buildings, but it should not be less than 0.8m. Cable to wear steel pipe wiring, should be reserved in the floor steel pipe, wiring should be completed after the plug fire fire blocking material. Cable bridge installation should be horizontal, the maximum sag should not be greater than 10 mm; proposed separate installation
Q:Cable YJV-3 * 70 + 2 * 35 general wear large SC tube? Ask you.
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:What does the letter of the computer cable model mean?
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
