Description

Grade 4214/4214B is suitable for 10kv and below medium and low voltage cable, it is composed by 95% silane crosslinkable low density polyethylene (compound A) and 5% catalyst (compound B). The main raw materials of the product are cable-use high-purity LDPE compound with mature graft technique and low impurity content, the product’s 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 cablesurface, high extrusion speed and production efficiency.

◆Extremely low impurity content and excellent electric performance.

Standard

After crosslinked in the tepid water, the cable made from the product grade 4214/4214B 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 of95:5) and be boiled in 90℃ water 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 4214/4214B.

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

165~175

175~190

190~200

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

Cooling water temperature: Should not be less 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 can be calculated according to the equation of 4hr/mm for 90℃.

Q: Engineering materials inspection, all types of cable wires should be issued a test report?: This approach is a lot of the general is to extend the city line, that is, line 220V AC line lengthened, some in Taobao. 2. to extend the low-voltage line, engage in a power plug on the plug, the same set of seats, you can easily do an extension line, when you want to use, docking about it, when you can not close up. This is also on Taobao, when to buy, pay attention to the socket, plug the model to the on.

Q: Apple phone display cable or accessories not certified how to do: Reply 3 # shops always have the door, and the door must be adjacent to the outdoor channel. Outdoor channel is public space! So the shop should be able to find the wiring channel. You have not encountered the situation, the map stickers out to see it?

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: Wire and cable CCC product consistency is what: PVC line, the market is better with plastic, plastic, . Wantong, etc., if only home improvement, then the brand requirements do not need so high. Small brands are the same, we see the quality. Network cable, then preferred Ann or TCL.

Q: Apple mobile phone does not support this charge when charging this thing how to charge: Charging line and the phone does not match, for the good point of the line just fine

Q: Decoration when the purchase of water pipes, wires and other items included in the account: KVV is the control cable, generally do industrial control; and RVS is twisted pair, generally used for weak system, to eliminate the interference requirements of the occasion, such as two-wire bus system, specifically, the electrical fire bus more Such as RS485 bus and so on.

Q: IPhone6 This cable or accessories have not been certified how to solve: The color is easy to distinguish. General yellow on behalf of the video line, red white plug left and right audio.

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: 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: Wire and cable fire resistance to meet what standards, which can provide about, thank you!: The electrical part of the decoration is laid by the electrician, as long as you tell him the power of your home and the equipment used, the electrician will tell you how much to buy the large diameter line, and the number and color needed.
