Mica Tape in Spool

product No:R-5461/FIRO
Unit:KG

Introduction
The mica tape length per roll is 500m~1000m in general. When one roll of mica tape is used up, replacing new mica roll takes much time. In order to save time, the tray is developed thereby. The longest length of tape in one tray can be up to 50000m(The tray diameter is 400mm and height is 400mm).


Types
According to the different reinforcing material, the products can be divided into:
R-5461-P-GS/FIRO-PGS Glass Backed Phlogopite Mica Tape
R-5461-P-FS/FIRO-PFS PE Backed Phlogopite Mica Tape
R-5461-P-GFD/FIRO-PGFD Phlogopite Mica Tape with Glass and Film
R-5461-S-GS/FIRO-SGS Synthetic mica tape with glass

Packaging
One pack is usually at 50kg, sealed with plastic film and packed in carton. The fumigation-free pallet shall be used when exporting. Each pallet contains <1000KG, or protected by metal drum.

Applications
The technicians should select appropriate width mica tape based on the wire sizes, winding tension, angles and wrapping speed, in case of broken tape or missed space, to ensure the surface of the insulated conductors after wrapping is smooth and flat, no mica falling off.
When winding small cross section wires, due to small coiling radius, the mica falls off easily. The width of the mica tape is small and the tensile strength is small, so the coiling tension and speed shall be uniform, in case tape broken and mica powder fallen off.
Mica tape wrapping layers and lapping rate are different when the material properties, specifications and models of the cables are different, and shall be determined by the cable designer based on the result of fire resistance test. According to IEC standard about fire-resistant cable testing, we recommend wrapping layers are 2 and the lapping rate is not less than 50%, i.e. the wire is wrapped by 4 layers of mica tapes.
