Description
Technical field
The utility model relates to electric wire field, is specially a kind of novel flexible fire prevention mineral matter cable.
Background technology
Traditional fire prevention mineral cable is BTTZ rigidity fireproof cable.It is filling as insulation filling that rigidity fireproof cable have employed magnesium oxide, magnesium oxide not only the most insulating barrier also as fireprotection layer.But magnesium oxide has following shortcoming as insulation: first easily the moisture absorption causes insulation resistance to decline, secondly rigidity fireproof cable is installed and is laid difficulty, again because being limited in actual production and work progress of this cable craft has a large amount of joints, that is cable can not be produced according to customer requirement measured length.Due to the above shortcoming of tradition fire prevention mineral matter cable, result in moistening at some weathers and lay in the longer engineering of distance and can not use in a large number.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of novel flexible fire prevention mineral matter cable, this cable can overcome the tradition fire prevention mineral matter cable easy moisture absorption makes absolutely edge resistance reduce and can not length quantity-produced shortcoming greatly, and the fire resistance test (950 DEG C × 180min) that can be specified by the BS6387:1994 of tradition fire prevention mineral matter cable " the cable performance requirement specification that holding circuit is intact in case of fire " equally, spray test and shock test.
In order to solve the problem, the technical solution of the utility model is: a kind of novel flexible fire prevention mineral matter cable comprises copper core conductor, fluorophologopite fireprotection layer, cross linked insulation separator, inorganic fire-retarded gasket for packing, high flame retardant oxygen barrier layer, stainless steel lock armo fireprotection layer, low smoke and zero halogen outer jacket, described copper core conductor is positioned at center, fluorophologopite fireprotection layer is wrapped outside copper core conductor, cross linked insulation separator extrudes and form single insulated wire cores outside fluorophologopite fireprotection layer, some insulated wire cores are twisted into cable core, inorganic fire-retarded gasket for packing is filled into insulated wire cores center in stranding process, high flame retardant oxygen barrier layer extrudes outside cable core, stainless steel lock armo fireprotection layer is wrapped outside high flame retardant oxygen barrier layer, low smoke and zero halogen outer jacket is extruded in cable outermost layer.
Described copper core conductor is the transmission conductor of cable, and conductor adopts and presses circular explained hereafter, and in order to avoid entering air, conductor compacting coefficient reaches 0.90, and conductor electrical performance and mechanical performance meet GB/T3956-2008 " conductor of cable " and specify requirement.
Described fluorophologopite fireprotection layer, material adopts synthesis fluorophlogopite belt.Mechanical performance compound GB/T19666-2005 " fire-retardant and fire-resisting cable general rule " the appendix C regulation of synthesis fluorophlogopite belt.
Described cross linked insulation separator, have employed crosslinked polyethylene as waterproof and moistureproof insulating barrier.Crosslinked polyethylene is applied to field of cables technology maturation, and insulation resistance can reach 18 powers of 10.There is excellent waterproof and dampproof performance.
Described inorganic fire-retarded gasket for packing, have employed high flame retardant glass fibre and adds continuous rope packing material.Due to insulated wire cores in cabling process in the middle of have space, and have oxygen in space can be combustion-supporting.In order to ensure the performance of cable, this inorganic fire-retarded gasket for packing of the fill gaps at cable core center.
Described high flame retardant oxygen barrier layer, have employed the low-smoke halogen-free polyolefin material of high flame retardant as oxygen barrier layer.This layer closely can be filled in the middle of cable core, thus plays and fire-retardantly add fireproof effect.
Described stainless steel lock armo fireprotection layer, adopting a wrapped composition lock armo copper sheath all linked with one another of stainless steel belt spirality, is main fireproof.
Described low smoke and zero halogen outer jacket, adopts orange low smoke and zero halogen sheath.Low smoke and zero halogen sheath adopts and squeezes tube process, and sheath outward appearance has allowed bellows-shaped.
Adopt the utility model can reach following effect: because stainless fusing point can reach 1450 DEG C, so the test request of 950 DEG C easily can be met with the utility model that interlocking armour stainless steel sheath is coated.Fluorophologopite fireprotection layer fusing point can reach 1375 DEG C, arrange in pairs or groups the energising that (can be greater than 180min) lastingly safe of common guarantee cable under 950 DEG C of flame, succour race against time for personnel escape in fire and fire-fighting with interlocking armour stainless steel sheath.The utility model adopts corrugated low smoke and zero halogen sheath in addition, and oversheath adopts orange, makes whole cable elegant in appearance.
