Abstract
The utility model discloses a two core composite cable are twisted with one heart in environmental protection and energy saving, including inner core and outer jacket, the inner core include inner conductor, cladding in the inner insulating layer on the inner conductor, cladding in outer conductor on the the inner insulating layer, cladding in external insulation layer on the outer conductor is constituteed, the inner conductor is formed by the transposition of thin monofilament, the inner insulating layer thickness is not less than the twice of the insulation thickness of related standard regulation, the outer conductor strands with the core type with the inner conductor, the inner insulating layer is exotic material with the external insulation layer, the outer jacket includes the oversheath. The utility model discloses a two core composite cable are twisted with one heart in environmental protection and energy saving compares with the two core composite cable that carry power, and the external diameter can reduce about 17%, and does not need the filler material, really accomplishes reduce cost, energy saving and consumption reduction.
Description
Technical field
The utility model belongs to composite cable field, is specifically related to a kind of environmental protection and energy saving and twists two core composite cables with one heart.
Background technology
Along with social development, the use amount of electric wire composite cable is more and more higher, and the material producing composite cable more and more lacks, and environment-friendly type energy-saving composite cable becomes the new trend of composite cable development.And traditional two core composite cables are owing to ensureing the rounding property of composite cable, often add more filler, and the effect that filler plays when the actual use of composite cable is almost nil, filler makes composite cable external diameter add, bring inconvenience to the installation of composite cable, use filler to cause composite cable cost to increase simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of environmental protection and energy saving, reduce composite cable external diameter, composite cable is installed and used twists two core composite cables more easily with one heart.
Two core composite cables are twisted in a kind of environmental protection and energy saving in the utility model with one heart, comprise inner core and outer jacket, described inner core comprises inner wire, be coated on inner insulating layer on described inner wire, be coated on outer conductor on described inner insulating layer, be coated on external insulation layer composition on described outer conductor; Described inner wire forms by thin monofilament is stranded; Described outer conductor and inner wire are that concentric type is stranded; Described inner insulating layer and external insulation layer are exotic material; Described outer jacket comprises oversheath.
Described inner insulating layer thickness range is 1.2 times of general standard regulation insulation thickness.Here, the insulation thickness that general standard specifies refers to, according to the general standard of cable, calculates according to core cross section, and if core cross section is 4.0 millimeters, then described interior insulation thickness is 1.0 millimeters.
Preferably, described inner wire forms by thin monofilament is stranded, and the diameter range of described thin monofilament is 0.3 millimeter to 0.68 millimeter.The thin monofilament of outer conductor can be consistent with the thin monofilament of inner wire, also other model can be changed, but in order to ensure that concentric type is stranded, need to calculate monofilament radical, to ensure that outer conductor can be coated in inner wire insulated wire cores uniformly according to the size of inner wire insulated wire cores external diameter.
Preferably, described outer jacket comprises armour, and described armour is coated on described external insulation layer, is made up of nonmagnetic substance.If it is non-armored type composite cables that two core composite cables are twisted in described environmental protection and energy saving with one heart, outside external insulation layer, extrude oversheath, if armouring composite cable, armoring material must select nonmagnetic substance.This better achieves the effect of electromagnetic shielding.
Preferably, the material of described oversheath is environmental-friendly halogen-free low-smoke cross-linked polyolefin.
Preferably, due to the change of composite cable structure, the cross sectional area range that two core composite cables are twisted in environmental protection and energy saving of the present utility model is with one heart 2.4-35 square millimeters.
Beneficial effect: environmental protection and energy saving of the present utility model are twisted two core composite cables with one heart and to be compared two core composite cables of same transmission power, and external diameter can reduce about 17%, and does not need packing material, really accomplishes to reduce costs, energy-saving and cost-reducing.Its efficiency of transmission is high, and effectiveness is good, substantially increases ground protection sensitivity and the reliability of composite cable.

Fig. 1 is schematic diagram of the present utility model.
Wherein, 1-inner wire, 2-inner insulating layer, 3-outer conductor, 4-external insulation layer, 5-oversheath, 6-inner core, 7-outer jacket, the thin monofilament of 8-.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Embodiment 1
As shown in Figure 1, two core composite cables are twisted in a kind of environmental protection and energy saving in the utility model with one heart, comprise inner core 6 and outer jacket 7, described inner core 6 comprises inner wire 1, be coated on inner insulating layer 2 on described inner wire 1, be coated on the outer conductor 3 on described inner insulating layer 2, the external insulation layer 4 be coated on described outer conductor 3 forms, described inner wire 1 forms by thin monofilament 8 is stranded, the diameter of thin monofilament 8 is 0.64 millimeter, and the structure of inner wire 1 is described inner insulating layer 2 thickness is 1.20 millimeters; Outer conductor 3 and inner wire 1 are that concentric type is stranded, and outer jacket 7 comprises oversheath 5, and the material of oversheath is environmental-friendly halogen-free low-smoke cross-linked polyolefin.
Be described in detail specific embodiment of the utility model above, but it is just as example, the utility model is not restricted to above description specific embodiment.To those skilled in the art, any equivalent modifications that the utility model is carried out and substituting also all among category of the present utility model.Therefore, not departing from the equalization conversion and amendment done under spirit and scope of the present utility model, be all encompassed within the scope of the utility model.
