Specifications

The tape is mainly used in the manufacturing of fire-resistant electric wire and cable.

Mica tape (for Fire-resistant wire & cable) consist of mica paper (phlogopite paper or synthetic mica paper), the non-alkali fiberglass cloth or Polyethylene film for reinforcement (single-side or double-side), and coupled by heat-resisting organic silicone adhesive, which is cut and processed into belted product after being baked and dried. It is featured in good insulation, fire resistance,good softness, ease of wrapping wires and cables. Hence, it is applicable to main fire-resistant insulation layers of various fire-resistant wires and cables.
Mica tape for fire-resistant wires and cables is mainly classified into the category A (950-1000°C) and B (750-800°C) base on the fire resistance grading. A may reach 1200°C,and the products in the category B are also able to normally work under the flame of 750°C for over 90 minutes.

Product Category:

Model	Name	Thickness	Application
NHJ-1	Single-side fiberglass enhanced phlogopite mica tape	0.12mm	B
NHJ-2	Double-side fiberglass enhanced phlogopite mica tape	0.14mm	B
NHJ-3	Fiberglass and film enhanced phlogopite mica tape	0.14mm	B
NHH-1	Single-side fiberglass enhanced synthetic mica tape	0.12mm	B, A
NHH-2	Double-side fiberglass enhanced synthetic mica tape	0.14mm	B, A
NHH-3	Fiberglass and film enhanced synthetic mica tape	0.14mm	B, A

Note: inner core is normally in 54mm, but can also be 76mm and 83mm; widths are available from 6mm, and when the width in 6-10mm, the outer diameter is about 240mm, can not be bigger; if the width bigger than 15mm, the maximum outer diameter can be about 340mm, but the production costs are higher too.

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: What brand of cable is good, what are the top ten brands of wires?: Power circuit box, the home of the circuit is divided into lighting, walls, air conditioning, etc., there is the bathroom and the kitchen line and the separation of the room.

Q: Engineering materials inspection, all types of cable wires should be issued a test report?: LCD TV can not be connected to the top of the box and DVD reasons: the connection line is wrong, you need to re-connect the video cable or high-definition multimedia interface line, component color line. . the first audio and video cable to DVD and LCD TV ("video 1" or "DVD" signal source); . Moreover, the set-top box and LCD TV (HDMI1 . the LCD TV, DVD and set-top box power are open; . according to the source selection, if you want to watch the DVD program, put the signal source to switch to the "high-definition multimedia interface cable (HDMI cable) Video 1 ", if it is to see the set-top box program, put the signal source to switch to" HDMI1 ". . so that put DVD and set-top boxes are also connected to the TV.

Q: Remove the computer and wash it off. What the motherboard did not move it, that is, the dust of those dust sasses, as well as the other wire of the skin what Sassafras wash, but the computer re-connected to the Internet when the old mistakes . and the lower right corner of the red Fork appears, disappeared after the emergence. The The Said the network cable is not plugged in, but the MODERN that POWER, LINK, LINE, 3 lights are normal display. The The This is how the matter, and just also appeared keyboard and mouse just start the machine can also be used normally, but in a moment to fall, and then plug their plug re-plug the mouse lights can be displayed, but the lights on the keyboard simply do not Bright, restart the computer but good, what is going on? bother. The The I hope the master quickly to help me, and this machine is relatively old ah No problem added: on a machine, just tried to re-create a connection in the network neighborhood, useless more: Galvanized pipe itself with anti-corrosion coating, you can not do anti-corrosion.

Q: 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...........................: I think it is possible, because in our (old) substation, the cable trench is the drain, the cable erected in the cable bracket.

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: Why this cable has not yet been certified: The manufacture of wire and cable is completely different from that of most electromechanical products

Q: This cable or accessory has not been certified and may not be able to work with this iphone reliably: Multi-core cable should be cable number, if not, should first use the table to find and put on the line with the tube.

Q: What are the T and T, s of the wire and cable test type?: May be charging head of the problem, the line may also be a problem. If the warranty can be free for the change.

Q: What is the warranty period for wire and cable?: Wire and cable warranty period is 30 years of national warranty period. But the specific warranty period according to the type of wire and cable and the use of conditions and temperature and applicable methods to determine. General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use.
