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: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: 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:Wire and cable: RVFV. : RVFSV. : UTP-CAT5E. : SYV-F-75-5 : RVFSP. : RVSP. : RVFVSP. What is the type of wire? Solve! More: Wipe with water that day. You can also use ink thinner

Q:Why does the bird stand on the wire without anything, but if people touch it,: Please provide air-conditioned three-leg socket photo, because you said "open inside is 2.5 square line ~ is a separate line ~" is not very understanding.

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?: 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.............................................

Q:Wire and cable model ZD what does it mean: Put the water clean, with a table to measure the insulation resistance between the lines, as long as no less than 1.5-2 can.

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:Apple phone display cable or accessories not certified how to do: Indicating that your Apple data cable is not original, no effect, re-plug the general and you can use the.

Q:Rt, the charger did not change, has been no problem before, today just plugged into the charger, the results appear as if the problem, before the out of this problem, and now only ipad power off after the power can not be charged, and ipad start , Then immediately prompted the title, can not charge more: The proportion of the cross-sectional area of the cable through the embedded pipe is 20%

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....: Then you get the repair station to see what is the problem

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.
