Application of synthetic mica tape in fire-resistant cable

Application of synthetic mica tape in fire-resistant cable

The application field of fire-resistant cable is gradually expanding, from the original offshore oil platform to aviation, aerospace, navigation, subway, tunnel, commercial building, hospital, dance hall, metallurgy, chemical industry and power plant, etc., which require high fire resistance rating. In recent years, with the maturity of the manufacturing technology of fire-resistant synthetic mica tape, the amount of fire-resistant cables manufactured with it is increasing. As we all know, the refractory mica tape is divided into two categories: *(950-1000 ℃) and B (750-800 ℃).

Refractory mica tape-Refractory insulation

High temperature resistance: synthetic mica belt fluorine gold mica belt, does not contain crystal water, melting point 1375 ℃, safety margin, high temperature resistance is the best, phlogopite releases crystal water above 800 ℃, high temperature resistance is the second, muscovite releases crystal water at 600 ℃, high temperature resistance is poor.

Calculation method of used quantity of polyethylene heat shrinkable winding tape

Heat shrinkable tape (open sleeve) is used to prevent corrosion at the welding place of two steel pipes. What is important is to use a set of heat shrinkable tape for one joint joint. The specifications are divided according to the pipe diameter and the price is sold according to one set. Therefore, a set of heat shrinkable tape will contain all the materials required for this weld joint corrosion protection: main tape; Epoxy primer; Fixing sheet; Adhesive tape.

How much do you know about wire and cable wrapping?

1. protect the insulation or inner sheath layer from damage to the armor when the cable is armored, and play the role of buffer and liner. 2. in the process of cable use, due to different materials on the cable insulation or inner sheath layer from heat insulation, or anti-corrosion, anti-aging and other different effects.

This article takes you to understand the difference between flame retardant cable, low smoke halogen free cable and fire resistant cable

Flame retardant cable is characterized by delaying the spread of flame along the cable so that the fire does not expand. Whether it is a single cable or a bundle of laying conditions, the cable is known to burn when the spread of the flame can be controlled within a certain range, so you can avoid the fire caused by the major disasters, thereby improving the fire level of the cable line.

What is halogen-free flame retardant belt?

Halogen-free flame retardant products with flame retardant level up to UL94-V0 standards, does not contain fluorine, chlorine, bromine, iodine halogen. Low smoke when burning, more environmentally friendly. The product has good self-adhesion, completely self-melting in a short time, no layering, and good sealing. The self-adhesive tape has good ductility, insulation and excellent physical properties.

Characteristics and identification method of low smoke halogen free flame retardant belt

The identification method of low-smoke halogen-free flame-retardant wire is the product name identification method. Wire-low smoke halogen-free flame retardant polyethylene insulated wire and cable; Cable-low smoke halogen-free flame retardant polyethylene insulated low smoke halogen-free flame retardant polyethylene sheathed power cable. Imitation under normal circumstances the name will be a little different, such as polyethylene insulation low smoke halogen-free sheath flame retardant power cable and so on;

The difference between flame retardant and low smoke halogen-free, do you understand?

Flame retardant cable is in the specified test conditions, the sample is burned, after the removal of the test fire source, the spread of the flame only within a limited range, residual flame or residual burning in a limited time can be self-extinguishing cable.

Performance and use of mica tape

Mica tape has good electrical and mechanical properties, has flexibility at room temperature, can be continuously wrapped around the motor coil, the main insulation of the motor coil by dipping or molding. Tung oil anhydride epoxy glass mica tape has excellent electrical and mechanical properties, good three-proof performance, high heat resistance, is the main insulation of high-voltage electric machine. Epoxy boron ammonium glass powder mica tape has a high heat distortion temperature, when the desired temperature is reached, can be quickly cured, easy to use. Organic silicon wafer or mica powder tape has high temperature resistance and is generally used for motor coil insulation above 180 ℃. Less rubber mica tape is mainly used for vacuum pressure integral impregnation of continuous insulation, with a certain degree of insulation strength and mechanical properties.
