Product Description:


Type of halogen free cables:
Installation cables
Power cables
Shipboard cables
Telecommunication cables


Halogen free cables
•    Installation cables (H05Z, H07Z, H07ZZ-F, NHMH)
•    Power cables (NHXHX, NHXCHX, NHXHX Fe 180, NHXCHX Fe180/E90, LiHXHX, LiHXCHX, LiHXHX Fe180, LiHXCHX Fe180, N2XH, N2XSH, N2XSEH,
•    Shipboard cables (FMGCH, MGCH, MGH, NFK FMGCH,  NFK MGCH, NFK MGH)
•    Telecommunication cables (J-02YSH, J-2Y(St)H, THI, THM, THN, THNE, THNE FE 20, THNe Fe180, ILAN 120 W H, TC 88 K (EK), TZ 88 e (Ge))
•    Cables for electronics (LiHCH, LiHH)

Basic requirements
Our halogen free power cables are notable for their improved performance in the case of fire, in addition to the requirements generally applying to power cables:
•    Low smoke density (firefighting and rescue operations made easier)
•    Reduced flame propagation (limited fire damage)
•    No corrosive combustion gases, owing to use of halogen-free materials (no danger to persons and no subsequent damages in the case of fire)

These three basic requirements are met by all Halogen free cables and verified by the following tests:
- Smoke density:
DIN VDE 0472 Part 816; IEC 1034
- Flame propagation:
DIN VDE 0472 Part 804, Test method C; IEC 332-3 Category A, B or C (Test on bunched wires or cables under fire conditions)
- Corrosivity:
DIN VDE 0472 Part 813; IEC 754-2
Additional fire tests:
- Circuit integrity of cable only:
DIN VDE 0472 Part 814; IEC 331
The stress duration for cables designated FE180 is 180 minutes.
- Circuit integrity of cable installation:
DIN 4102 Part 12;
This test according to building legislation differs essentially from the tests according to VDE. No longer is the cable examined alone (test on circuit integrity of cable only), a complete installation (cable installation) undergoes testing. Apart from the cable, the cable installation includes support devices, connecting elements and mountings. A detailed test certificate is issued for the test performed. Circuit integrity of cable installation is classified as E30 (30 min.) and E90 (90 min.) respectively, depending on the stress duration.

Q:There is no air conditioning in the small room with a replacement patch panel.
Sce did not understand your meaning, do not know what you want to ask.
Q:What is the position of the wire in the wall?
It shows that the design is unreasonable The correct approach is that there is a special cable wells in the best, however, the general construction unit is too expensive to save this may be bitter construction units continue to repair, it is difficult to cure here to introduce a few ways, According to the situation selected: . casing filled with dry cement, and with a wooden hammer tamping, but a certain idea of security, high pressure line once rammed the skin is too dangerous, should be done before power, you now estimated to have power, . outside the set of electric wells, the depth of the bottom of the casing in the 1 meter or so, and the wells do waterproof, wellhead should be hardened around, to avoid rain immersion, you seem to have done, but do not good enough, at the same time Into the built-in automatic suction pump, rain more than a certain depth of automatic drainage, is the price slightly higher; . in the cable casing surrounded by water swelling type of water, such as BW Zhishui, etc., but the effect in general.
Q:How can the most effortless way to put the cable on the bridge
Wiring this problem depends on how much of the current you want to use the general 10 square below the wire per square (aluminum) can pass 5 current (copper line l, but I are using copper per square 5 current) current Generally on the school should be considered P = IU (P power I current U voltage
Q:What is the difference between wires and cables? Please provide a brief introduction
Copper and aluminum single-core wire 50 into the point of the cable 10 or less As for the accessories that should be just as large as the cable will not enter the high cost as long as the good manufacturers like, who want goods, immediately called the manufacturers made. The first two days to go, choose to do business you see who has so much cable at home, ah, are manufacturers direct delivery
Q:Wire production is not to be a few meters ahead of the extension line
10 square to wear . 16 square . 35 square . 50 square . if it is copper or turn more PVC pipe should be enlarged on the 1st. Polyvinyl chloride (English: PolyVinylChloride, referred to as: PVC) is a use of a chlorine atom to replace polyethylene in a hydrogen atom of the polymer material. PVC is an amorphous structure of the white powder, the degree of branching is small. Industrial production of PVC molecular weight is generally in the range of 5 to 12 million, with a large polydispersity, molecular weight increases with the reduction of polymerization temperature. No fixed melting point, 80 ~ 85 ℃ began to soften, 130 ℃ into a viscous state, 160 ~ 180 ℃ began to change into a viscous flow. Its tensile strength of about 60MPa, the impact strength of 5 ~ 10kJ / m2; has excellent dielectric properties. The stability of light and heat is poor, above 100 ℃ or prolonged sun exposure, it will decompose and produce hydrogen chloride, and automatically catalyze the decomposition caused by discoloration, in practical applications must be added stabilizer to improve the stability of heat and light. PVC is very hard, can only be dissolved in cyclohexanone, dichloroethane and tetrahydrofuran and a few solvents, the organic and inorganic acids, alkali, salt are stable, chemical stability with the use of temperature rise.
Q:Please use the CPU power to extend the line of people come in! Thank you
Voltage levels are 300 / 300V, 300 / 500V, 450 / 750V, 0.6 / 4kV, etc., which is commonly used voltage level. When ordering according to your use of environmental conditions, use the size of the load and voltage level selection. Inspection can only test the size and appearance of the structure, some electrical parameters need special equipment to measure, you can measure the insulation thickness, conductor diameter, insulation diameter and so on. General wire and cable to buy some formal large enterprises, although there are losses side of the phenomenon, but generally its electrical performance can guarantee.
Q:5 4 * 95 + 1 * 75 cable should choose what size of the bridge
WDZD-BYJ is halogen-free low smoke flame retardant single-core fabric wire, no sheath. WDZB-YJY is a halogen-free low smoke flame retardant cable with a jacket.
Q:What is the meaning of PG + digital markings for electrical wiring?
RVV - Copper core PVC insulated PVC sheathed cord. RVS - Copper core PVC insulated stranded cord. KVV - Copper core PE insulated PVC sheathed control cable. RVVP - Copper core PVC insulated PVC sheathed shielded cord.
Q:10KV high-voltage cable and heating pipe cross the safe distance
And the thermal pipe ditch parallel to the distance of 2 meters, the special circumstances can be reduced and reduced by half the value; cross-distance 0.5 meters, separated by a partition or cable pipe can be 0.25m see GB-94 Table 5.3.5 2006 version of the basic out or the implementation of this, to the local power supply management advice prevail
Q:Pads in the painting PCB how to modify the line width in batches, or unified to amend the line width, the best with screenshots, you can add points Kazakhstan
It is recommended that you buy a TV card price of 100 yuan, with it can watch TV on the computer, it also has a collection function, you can simulate the signal directly to the computer to become a DVD or VCD MPG file, such as the gallbladder There is a need to make a disc. It is recommended to buy PHILIPS chip
