RB-FC08

Metal composite fire protection sleeve

Product specifications：

Length 100Omm, inner diameter 12~13cm (octagonal)

Product introduction：

The product is made of stainless steel plate, fireproof layer, steel wire mesh, aluminum foil four layer structure. The maximum fire-proof effect can be up to 3 hours, its core is a layer of thermal expansion refractory layer. When the product is subjected to high temperature, such as fire and heat, it will produce an expanding carbonaceous layer, which can prevent the threat of radiant heat,flame expansion and smoke, can maximize the protection of life and property safety, reduce fire losses.

Installation Notes

1.Rigid Bend: adopt special connector device to realize flexible and flexible bend, suitable for wide bending cable working condition;

2.Flame insulation: thermal expansion, effectively prevent the spread of fire, to ensure that no damage to the surrounding cable;

3.Blocking Smoke: effectively prevent the spread of smoke, to protect personnel, equipment from the threat of smoke;

4.Heat insulation: effective prevention of heat conduction caused by the back of the spontaneous combustion, thus preventing fire spread

5.Water tightness: with water tightness, to achieve effective waterproof function;

6.Anti-ablation: in case of fire, it can keep the whole structure intact and not collapse:

7.Durability: long-term availability before fire

	Performance indicators	Typical values
1	Fire resistance	When the fire test is carried out for 90 minutes, the leakage current of the cable deposited in the test piece does not reach 3A，the fuse of 3A is not broken，the fire resistance is not lost， and the working time is 90 minutes, the fire resistance is over 90 min and reaches F1 grade
2	High current temperature rise test	After the installation of metal composite fire protection sleeve,the stable temperature of the cable after heating up is less than 5℃ compared with that before installation
3	Impact test	Shell withstands 7J impact energy， no damage
4	Waterproof grade	IPX7
5	Heat and cold resistance test	No significant change
6	Vertical combustion test	V-0
7	Halogen，Asbestos	Not inc luded
8	Toxic smoke	Achieve safety level 1 AQ1 (smoke-free poison)

It is suitable for the fire-proof separation treatment of high-voltage and low-voltage common trench cables, especially for the passageways with many cable turns and dense cable laying, each 10KV cable is wrapped and separated by metal composite fire-proof bushing
