Description

Grade 4214N/4244N is sioplas (two steps) natural curing silane XLPE compound, it is composed by compound A and compound B.Compound A is high-quality special polyethylene material with unique grafting process, while compound B adopts the advanced catalyst system. The product can be quickly crosslinked in hot water or after some time exposed in the air, it is suitable for 3kv and below low voltagecable. The major characteristics are

◆Quick crosslinking speed, not necessary be boiled in hot water, simplify the procedure, and improve the production efficiency and cost saving.

◆Non-corrosive to the equipment line, non-corrosive to copper conductor.

◆Less affected by the masterbatch.

Grade 4214N is suitable for the extrusion method of squeezing extrusion,half-tubing extrusion and tubing extrusion; grade 4244N is suitable for tubing extrusion method.

Suitable for small cable with cross sectional area equal to or larger than1.5mm2.

Halogen free, and environment friendly.

Standard

Performance test is in accordance with JB/T 10437-2004 standard. The cable made from the product grade 4214N/4244N 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), double-sided exposure in the constant temperature and humidity box (23℃, relative humidity 75%) and measured after 48 hours.

*Especially, these typical values were tested on fully solidified and cured sample (If the sample is not fully cured, it will continue the curing during ageing procedure, and consequently will affect the test result before and after heat ageing).

**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 one hour.

Recommended Processing Technique

1.   Extrusion Equipment

The product is easy to be plasticized, ordinary PVC-use single screw extruder (length-diameter ratio is 15 to 20) can be used,the equipment requirement is relatively simple screw structure and the flow wayis smooth and no dead end.

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:

Die head setting:
4214N is suitable for squeezing extrusion style, half-tubing extrusion style and tubing extrusion style. 4244N is suitable for tubing extrusion method. To produce with tubing extrusion style, the recommended draw ratio is less than 1.2 (4214N) / 1.3(4244N), the greater the draw ratio the greater the thermal shrinkage.

Cooling water temperature: Should not be less than 25℃,gradual cooling water tank is recommended.

Conductor temperature: Appropriate warm-up the copper or aluminium conductor, which can further reduce the heat shrinkage of the insulation and accelerate the cross link speed.

   

Crosslink Speed

For the cable made from this material, the cross link speed has close relation tothe insulation thickness, ambient temperature, environment humidity and coilsize. The thinner and smaller the coil size, the higher temperature and humidity, the shorter the time needed for cross linking. During cold and dry winter season, the crosslink speed in natural environment will be comparatively slow down. To reduce the cross linking time, it is recommended to spray somehot water on the surface of the insulation to accelerate cross link procedure.

Q:Seeking the basement of the outer wall piercing the cable after the casing, how to solve the water (200 points online)
To be considered is the Great Wall power line is not long enough, the power is not big enough to see the power on the label, if the 12V to 15A or more I think will be more stable, my Dell machine power cord surprisingly short, but also To buy the extension line again.
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
