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: Apple 6splus charge may not support this accessories how to do more: When the lighting circuit and the power circuit shared ladder, BV line is not allowed to put in the ladder, so it is recommended to use the wiring of the lamp ZC-YJV-3 * 2

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 itself on the anti-corrosion, no need to do anti-corrosion treatment.

Q: How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more: According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.

Q: Decoration when the purchase of water pipes, wires and other items included in the account: Outdoor fire line must use fire-resistant KVV cable, wear pipe protection.

Q: IPhone6 This cable or accessories have not been certified how to solve: Labor costs you can and workers to discuss, and some labor costs are calculated in accordance with square meters, and some are calculated in accordance with the day, the specific or ask the local construction team

Q: Wire and cable model ZD what does it mean: Wire pipe water problem: In fact, this problem is very serious, then this line should be scrapped or replaced, if you continue to reluctantly use not only to bring you the safety of trouble and the insulation of the wire dropped sharply! Because there is water it will lead to internal leakage can also make the wire heat caused by wire burning and trivial trivial accident, so be sure to take the necessary replacement! Supplement: the wire out of all, with the wire to grab the absorbent gauze and the like back to the twitching, many times for the gauze to dry the water, hair dryer toward the tube to heat the tube to dry and then re-layout of the new line.

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: 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: This cable or accessory has not been certified and may not be able to work with this iphone reliably: The installation process is a certain requirement, high and low voltage cable bridge should be installed separately as usual, a wall laying vertical pipeline (slot) or installation equipment, the power distribution between the depth of D1 = 1200 ~ 1500mm; weak Between the deep distance from the D2 = 1100 ~ 1400mm more reasonable. The length L1 and L2 between the power distribution and the weak can be determined according to how much electrical equipment and pipelines (slots) are installed in the room. "Civil building electrical design specifications" proposed "shaft size in addition to meet the wiring spacing and terminal box, distribution box layout must be the size, but also in the box before the left not less than 0.8m operation, maintenance distance" requirements. In the weak equipment, the operation and maintenance distance is not specified in the provisions of the Code for Electrical Design of Civil Buildings, but it should not be less than 0.8m. Cable to wear steel pipe wiring, should be reserved in the floor steel pipe, wiring should be completed after the plug fire fire blocking material. Cable bridge installation should be horizontal, the maximum sag should not be greater than 10 mm; proposed separate installation

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!
