Abstract
The utility model discloses an installation cable of an engine of large machinery. The installation cable comprises three insulating cores which are distributed in a triangle, a vibration-proof pad is arranged among the three insulating cores, and is formed by a thermoplastic elastomer via plastic extrusion; and the three insulating cores and the vibration-proof pad form a cable core, an aluminum-foil taped covering and a calcined mica taped covering are successively arranged outside the cable core, a vibration-proof layer which is molded by crosslinked polyethylene via plastic extrusion is arranged outside the calcined mica taped covering, multiple vibration-proof holes are distributed in parallel along the axial direction of the cable core in the vibration-proof layer, and an oversheath layer is formed outside the vibration-proof layer via plastic extrusion. The installation cable uses multiple vibration-proof structures as the vibration-proof pad and the vibration-proof layer, stable and reliable work of the installation cable under a working environment with continuous vibration is ensured, the whole cable is not easy to deform, and the installation cable has excellent shielding, extrusion-resistant and high-temperature-resistant performance.
Description
technical field:
The utility model relates to electric wire, relates in particular to a kind of big machinery engine installing cables.
background technology:
Being accompanied by automation, high-technicalization advances rapidly; the various metered quantities of installing on the engine of numerous big machineries in the market increase; number of cables is also increased relatively; but engine can produce vibrations frequently in the course of the work; often can cause cable yielding impaired; when serious, cause the operation irregularities such as instrument, thereby affect the normal use of equipment, reduced operating efficiency.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of big machinery engine installing cables, simple in structure, has good anti-seismic performance and anti-extrusion performance, have simultaneously lightweight, compactedness good, resistance to elevated temperatures.
The technical solution of the utility model is as follows:
Big machinery engine installing cables, comprise three insulated wire cores that distribute in a triangle, it is characterized in that: the center of three described insulated wire cores is provided with antidetonation cushion, antidetonation cushion adopts thermoplastic elastomer (TPE) extrusion moulding, three insulated wire cores and antidetonation cushion form cable core jointly, the outside of cable core is provided with aluminium foil strip lapping layer successively, calcining Mica tape layer, calcining Mica tape layer outside is provided with the antidetonation layer of crosslinked polyethylene extrusion moulding, antidetonation layer is interior along be distributed with some roads shock relieve vent parallel with cable core axial direction, outside antidetonation layer, extrusion moulding has external sheath layer.
Described big machinery engine installing cables, is characterized in that: between described aluminium foil lapping layer and calcining mica belt, be provided with drainage band, drainage band and aluminium foil lapping layer fit tightly.
The utility model has the advantages that:
The utility model adopts multiple shock-damping structure, by designs such as antidetonation cushion, antidetonation layers, guarantees reliable and stable work under the operational environment that continues vibrations, and whole cable is not yielding, has good shielding properties, anti-extrusion performance, resistance to elevated temperatures simultaneously.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
