Description
Grade 4215 is specially used for 10KV below aerial hanging power cable, it is composed by 90% silane crosslinkable low density polyethylene (compound A) and 10% black catalyst (compound B). The product has outstanding performance in anti-ageing property, wild processing temperature,easy processing characteristics and excellent product quality.
Standard
After crosslinked in the tepid water, the cable made from the product grade 4215 can comply with the standard of IEC60502-2004, GB/T14049-2008.

Typical values 1-4, 11 were tested on the sample strip by squeezing film extrusion after mixing compound of A & B (at percentage of 90:10) and be boiled in hot water at 90℃ for 4 hours.
*Especially, these typical values were tested by press moulding sample (A and B mixed atpercentage of 90:10), 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 4215
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 be based on different equipment and pressing conditions, reference settings are as following:
Feeding Section（℃） | Compression Section（℃） | Measurement Section （℃） | Die head and Mould （℃） |
150~165 | 165~177 | 175~190 | 190~200 |
Die head setting: Squeezing extrusion style and tubing extrusion style
Cooling water temperature: Should not be less than 25℃, when using tubing style extrusion method, gradual cooling water tank is recommended for better control the heat shrinkage.
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: 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: What brand of cable is good, what are the top ten brands of wires?
- If you are talking about the three-core wire, black - ground brown - line of blue - zero line. If it is 3 plugs, your wire is only 2 lines. Then the yellow received L, black received N. The above is the ground wire.
- Q: What machinery is required to make wire and cable?
- Pouring concrete when you can line? Do you clear the problem?
- Q: IPadmini. The latest version 7.1.1 up in the morning to see the non-stop display this cable is not certified does not support this feature. The The Charger original. Not on the computer charge. The Ask God to answer more
- Data line problem, it may be the data line to the bad, caused by poor contact. For the sake of the root
- Q: What is the difference between wires and cables?
- The introduction of the device in the form of: sealing ring (sealing ring is to achieve the required protection level of the shell and the use of cash-saving brush to help find the silent material or elastic material parts) type of introduction device; casting solidified packing seal Type introduction device; metal seal ring introduction device
- Q: IPhone mobile phone data cable can not charge the power, the above shows the cable or accessories not certified can not work with the iPhone,
- Not allowed to slot the proposal with PVC gusset which is only 1 cm thick only open protective layer on it! The water pipe is not enough unless you have a thickened wall outside the decoration.
- 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
- Megohmmeter, such as measuring insulation normal, that is, induction power, the other line after grounding, the pen measured no electricity.
- 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: 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: What are the T and T, s of the wire and cable test type?
- You should be said: 2-way cross-linked polyethylene insulated PVC sheathed cable 4 core 185 square millimeters, SC is steel pipe, diameter . FC is laying method dark cover the floor or floor. Personal opinion, hope to help you!
