Abstract
The utility model discloses an environmental-friendly saving type foaming filling strip which comprises a filling strip body, wherein a part where the filling strip body is in contact with a cable, is provided with a concave surface adapting to the cable in shape; and the concave surface is preferably a semi-circular concave surface with the diameter of 1.2 times that of the cable. In order to save materials and reducing the weight, a circular hole is arranged in the filling strip body. The environmental-friendly saving type foaming filling strip is light in weight, is soft in texture, provides a reliable safety and insurance pit for an optical fiber through arranging the concave surface adapting to the cable in shape on the part wherein the filling strip body is in contact with the cable, and accords with the performance requirement of the filling strip for a crosslinked polyethylene insulation fiber composite power cable. The environmental-friendly saving type foaming filling strip is low in production cost, realizes recycling of wastes, is a novel environmental-friendly saving type foaming filling strip, and complies to the development law of the modern cable industry.
Description
Technical field
The utility model relates to a kind of fiber composite power cable, specifically is foam filled that adopts in the cable.
Background technology
At present cross-linked polyethylene insulated cable is for guaranteeing the roundness of cable, and product quality, all the stranding operation in addition filler fill up the space, filler has fan-shaped packing, circular packing and gasket for packing etc., wherein uses more extensive with fan-shaped packing.High speed development along with Chinese national economy; Demand to electric power increases substantially, and national grid has proposed to set up unified intelligent grid, has determined national grid development in future direction; This just requires links such as generating, transmission of electricity, power transformation, distribution, electricity consumption can reach organic assembling; And each link of require forming this system will realize intellectuality, realizes the electrical network of intelligent automatic balance self-monitoring, the cable of using for electric energy transmitting; Require it not only can realize the basic function of conduct electrical energy; Also should cooperate with pertinent instruments (like the distributed optical fiber temperature measurement appearance), optical cable just needs and cable combination like this, and Optical Fiber Composite power cable with cross-linked polyethylene insulation cable is mainly with the gap location of optical cable cell distribution at the stranding cable core at present; And packing just in time contacts with cable core and optical cable generation during this time; The processing mode of prior art need cause the metallic conductor cable core in case dislocation takes place and very easily dampen the optical cable unit, and prior art not considered that packing can play the certain protection effect with the optical cable unit with metallic conductor cable core stranding.
The utility model content
The utility model is to the deficiency of prior art, and a kind of foam filled of environmental protection and saving type that optical cable do not receive the injury of metallic conductor cable core of in fiber composite power cable, can effectively protecting is provided.
Foam filled of the described environmental protection and saving type of the utility model comprises the packing body, is provided with and the suitable concave surface of optical cable shape at packing body and optical cable contact site.
Said concave surface is preferably semicircle concave surface, and the diameter of semicircle concave surface is 1.2 times of optic cable diameter.
In order to save material and weight reduction, on the packing body, be provided with circular hole.
Beneficial effect: the utility model is not only in light weight; Quality is soft; And through being provided with and the suitable concave surface of optical cable shape at packing body and optical cable contact site; For optical fiber provides reliable safety assurance " cave ", meet the performance requirement of crosslinked polyetylene insulated fiber composite power cable with packing.Production cost is low simultaneously, has realized waste recycling, is that a kind of novel environment-friendly type is practiced thrift foam filled, has complied with the rule of development of modern cable industry.
Description of drawings
Fig. 1 is the utility model structure chart.
Embodiment:
As shown in Figure 1, on the packing body 3 of the utility model, be provided with semicircular concave surface 2 with the optical cable contact site, its diameter is 1.2 times of optic cable diameter.In addition, on packing body 3, also be provided with circular hole 1.
The utility model is foam filled the improvement of carrying out that crosslinked polyetylene insulated fiber composite power cable is used; Its manufacture process is: crosslinked cable is driven material and the cable jacket material scrapped is pulverized; Add ADC blowing agent etc. again and produce cable filler strip, form a circular hole 1 in the packing cross section through extrusion die, its diameter is not more than 15mm; Not only practice thrift cost, and alleviated the weight of cable.Simultaneously make semi-circular concave surface 2 at the packing edge, its diameter is 1.2 times of optic cable diameter, for round fiber provides reliable safety " cave ".
