Fig. 2 is the insulating layer structure figure of the utility model embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with the embodiment that attached drawing provides.Described implementation
Example includes the various details for helping to understand, but they can only be counted as illustratively, be a part of the utility model
Embodiment, instead of all the embodiments.Unless otherwise defined, the technical term or scientific term used herein should be this
The ordinary meaning that personage in utility model fields with general technical ability is understood.Meanwhile in order to keep specification more clear
Chu is succinct, by omission pair it is well known that the detailed description of function and construction.
As depicted in figs. 1 and 2, a kind of flame-retardant environmental protection optical cable, including light unit component 1 and setting are in the light unit
Thermal insulation layer 2, flame retardant bed 3, interior steel-tape armouring layer 4, inner sheath 5, outer steel wire armor layer 6 and the oversheath 7 in 1 outside of component, institute
Thermal insulation layer 2, flame retardant bed 3, interior steel-tape armouring layer 4, inner sheath 5, outer steel wire armor layer 6 and oversheath 7 are stated from inside to outside in same
Heart round shape is sequentially sleeved at 1 outside of light unit component.
The light unit component 1 includes optical fiber 10, ointment 11 and Loose tube 12, and the optical fiber 10 is set in ointment 11,
The Loose tube 12 is set in outside ointment 11.
The thermal insulation layer 2, flame retardant bed 3, interior steel-tape armouring layer 4 and outer steel wire armor layer 6 surface setting nothing is respectively coated
Halogen Flame-retardant environment-friendlymaterial material layer.
The inner sheath 5 is tubulose low-smoke non-halogen flame-retardant environmental protection sheath.
The oversheath 7 is tubulose low-smoke non-halogen flame-retardant environmental protection sheath.
The flame retardant bed 3 is tubulose mica.
The thermal insulation layer 2 is the latticed circle tube member being set in outside light unit component 1.
The thermal insulation layer 2 is separate structure, including the first insulating unit 21 and the second insulating unit 22, and described first is heat-insulated
Unit 21 and 22 split of the second insulating unit are cylindrical shape.
According to a kind of flame-retardant environmental protection optical cable of the application, include light unit part (optical fiber+ointment+Loose tube),
Middle Loose tube increases the setting of 20%-50% using more universal optical cable wall thickness.
According to a kind of flame-retardant environmental protection optical cable of the application, on the outside of light unit using thermal insulation layer+flame retardant bed (flame retardant coating)+
Steel-tape armouring layer+low-smoke non-halogen flame-retardant environmental protection inner sheath constitutes second layer refractory system.Wire armoring knot is used on the outside of inner sheath
Structure+low-smoke non-halogen flame-retardant environmental protection oversheath constitutes first layer refractory system.
First layer refractory system uses there are two LSOH anti-flaming composite material oversheath+steel wire armoured effects.?
In the case where not having open fire, oversheath has fire-retardant characteristic；When having open fire, after oversheath is burnt by open fire, flame
It directly burns in steel wire armor layer, steel wire is non-combustible metal material, even if covering it from 100% because of the problem of technique
Cover inner sheath.But because the incendiary material being exposed on the outside of flame is limited, prevents it from burning well, delay flame
The time penetrated.Second effect of steel wire armor layer is to strengthen optical cable tensile characteristic.
The fire-resistance property of second layer refractory system is more perfect, and in the case where no open fire, inner sheath has fire-retardant
Characteristic；When having open fire, after inner sheath is burnt by open fire, steel-tape armouring layer is 100% area armouring, the inside of armor
For mica flame retardant coating, using wrapped production technology is put up, overlap rate is not less than 45%, in a tubular form 100% covering inside every
Thermosphere prevents flame from penetrating inside after flame penetrates first layer.In addition, other each layers are equal in addition to light unit material is not fire-retardant
It can be directly used or coat halogen-free flame-proof environmental protection material, reinforce flame retardant effect.
The thermal insulation layer 2 is that heat leak enters cable interior in order to prevent, influences transmission and the cable lifetime of signal.
The thermal insulation layer 2 can be totally enclosed, be also possible to engraved structure, to mitigate weight.It is mainly hot using air
The principle of non-conductor reduces heat and internally transmits.Engraved structure is divided into two, and can be led to by upper and lower two parts in production
It crosses mold and pieces together an entirety, convenient for manufacture.The thermal insulation layer 2 can use plastics or rubber or other suitable compound
Material is made.
According to a kind of flame-retardant environmental protection optical cable of the application, the fire-protection rating than general optical cable is more increased, can be born
The time of flame combustion is longer.The use of thermal insulation layer can make the time of the incoming light unit part of ambient temperature elongated.It can
It prevents from being burned out in the optical cable short time, still can be carried out data transmission when bearing open fire burning in short-term.
The use of halogen-free material does not generate pollution to environment, and smog will not be generated and have by being burned under open fire state
The harmful substances such as malicious halogen.
The promotion that flame-retardant performance is carried out using Double-layer flame-retardant refractory system constitutes structure by the double-deck refractory system,
It may insure the reliable of flame-retardant and environmental-protecting performance.Outside characteristic with fire resisting, tensile characteristics are also very prominent, fire in flame
When burning, certain pendency can be kept to stablize the time.
"upper" described herein, "lower" or " top ", " lower section " or similar term are the placement shapes with normal use
Relativeness for state, that is, the positional relationship that illustrations are substantially shown.When placement status changes, such as
When overturning, corresponding positional relationship should be also converted therewith to understand or implement the technical solution of the application.
