Abstract
The utility model discloses a modified ternary silicon rubber insulation cable which comprises four conductors on which insulation layers are wrapped, wherein the conductors on which the insulation layers are wrapped are mutually twisted into a beam by using a reinforcing core with a rhombic section as a center to form a cable core, an elliptical tin-plated steel wire is arranged in the reinforcing core, a lapping layer is wrapped outside the cable core, a filling layer is arranged between the lapping layer and the cable core, and a sheath layer is wrapped outside the lapping layer. The modified ternary silicon rubber insulation cable has a reasonable structure design; the elliptical tin-plated steel wire is arranged in the reinforcing core at the center of the cable core, so that the cable core becomes a tensile cable core, and the structure strength of the cable core is remarkable enhanced; and a fire-resistant and flame-retardant material is adopted in the filling layer, the water resistance and the flame retardance characteristics are improved, and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to the silicone rubber for cable field, relates in particular to a kind of modification ternary silicon rubber insulated cable.
Background technology:
Ethylene-propylene diene copolymer is used at cable industry because of its good electric property, mechanical and physical performance and excellent processing characteristics widely.Because the oxygen index of ethylene-propylene diene copolymer self lower (oxygen index only 17) has caused the use field to get limitation.
Substitute calcium carbonate and potter's clay in the ethylene-propylene diene copolymer prescription with nano imvite, nano aluminium oxide, nano magnesia, traditional ethylene-propylene diene copolymer prescription is carried out modification, can fully improve the oxygen index (oxygen index can reach 25) of ethylene-propylene diene copolymer.Nano imvite is good reinforcement and fire retardant, and nano aluminium oxide, nano magnesia utilize crystallization water volatilization to absorb heat in combustion process owing to himself contain the crystallization water, realize the halogen-free flame-retardant of ethylene-propylene diene copolymer.Nanometer materials simultaneously because its excellent surperficial affinity, can not produce destruction to the mechanical and physical performance and the electrical property of ethylene-propylene diene copolymer.Using low smoke and zero halogen ethylene propylene diene rubber after the modification for insulation, is sheath with the low-smoke halogen-free polyolefin material, is that the environment-friendly cable overall performance of filling gets a promotion with heat-resistant fireproof materials such as glass rope and glass fibre belts.
The structural strength of cable conductor can not well satisfy the demand of actual working environment in addition.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of modification ternary silicon rubber insulated cable, and reasonable in design is adaptable across the mine, subway and nuclear power, skyscraper field.
The technical scheme of the utility model is following:
Modification ternary silicon rubber insulated cable; The conductor that comprises four wrap insulate layers; It is characterized in that: the conductor of wrap insulate layer is that the strengthening core of rhombus is that the mutual stranded bunchy in center constitutes cable core with the cross section, is provided with oval-shaped tin plated steel wire in the strengthening core, and cable core is wrapped with lapping layer; Be provided with packed layer between lapping layer and the cable core, lapping layer is wrapped with restrictive coating.
Described modification ternary silicon rubber insulated cable is characterized in that: it is the several layers of overlapping wrapped formation of glass fibre belt that described lapping layer adopts material, and the wrapped rate of putting up is not less than 36%.
Described modification ternary silicon rubber insulated cable is characterized in that: described packed layer adopts glass rope or glass fibre belt to fill formation.
The utility model has the advantages that:
The reasonable in design of the utility model is provided with oval-shaped tin plated steel wire in the strengthening core at cable core center, make cable core become the tension cable core; Structural strength obviously strengthens; Packed layer adopts the material of fire resistant flame retardant, has improved the fire resistant flame retardant characteristic, has prolonged the useful life of cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Modification ternary silicon rubber insulated cable; The conductor 1 that comprises four wrap insulate layers 2; The conductor 1 of wrap insulate layer 2 with the cross section be the strengthening core 3 of rhombus for the mutual stranded bunchy in center constitutes cable core, be provided with oval-shaped tin plated steel wire 4 in the strengthening core 3, cable core is wrapped with lapping layer 5; Be provided with packed layer 6 between lapping layer 5 and the cable core, lapping layer 5 is wrapped with restrictive coating 7.
It is the several layers of overlapping wrapped formation of glass fibre belt that lapping layer 5 adopts material, and the wrapped rate of putting up is not less than 36%.
Packed layer 6 adopts glass rope or glass fibre belt to fill formation.
