Description

Composite reinforced flat cable for new bucket wheel machine

technical field

The utility model relates to the technical field of electric wires and cables, in particular to a new composite reinforced flat cable specially used for a bucket wheel machine.

Background technique

When the bucket wheel machine works, it is a back and forth motion. Because the cable moves with the equipment, the cable moves back and forth very frequently, resulting in a very short service life. In the past, separate power cables and control cables were usually laid on both sides of the equipment. This brings inconvenience to equipment installation and operation.

Contents of the invention

The purpose of this utility model is to provide a new type of composite reinforced flat cable for bucket wheel machines, which uses steel wire to strengthen the conductor core, and puts the control cable and power cable together to make a composite reinforced flat cable, thereby overcoming the inconvenience of equipment installation and operation The problem.

In order to achieve the above object, the technical solution proposed by the utility model is:

A new type of composite reinforced flat cable for bucket wheel machines, including multiple power cores and a control core, the multiple power cores and a control core are arranged side by side in the outer sheath; each of the The root power core includes reinforcement core 1, power core conductor, conductor shield, insulation 1, insulation shield, and reinforced shield from inside to outside; the control wire core includes reinforcement core 2, control wire core conductor, insulation 2, inner Sheath, the reinforcing core 2 and the control core conductor are wrapped with the insulating 2, the reinforcing core 2 is one, the control core conductors are multiple, and the multiple control core conductors are round The shape is distributed around the reinforcing core 2, and the inner sheath is wrapped around the periphery of the plurality of control core conductors wrapped with the insulating 2.

As a further improved composite reinforced flat cable for bucket wheel machines of the present invention, the first and second reinforcing cores are soft steel wires.

As a new type of composite reinforced flat cable for bucket wheel machines that is further improved by the utility model, the conductor shield and insulation shield are semi-conductive nylon tapes, the insulation one is ethylene-propylene rubber insulation, and the reinforcement shield is tinned copper wire braiding shield.

As a new type of composite reinforced flat cable for bucket wheel machine further improved by the utility model, the insulation two is ethylene-propylene rubber insulation, the inner sheath is a rubber sheath, and the outer sheath is a butadiene-silicone rubber sheath.

The new composite reinforced flat cable for bucket wheel machines provided by the utility model needs to be continuously bent back and forth, so soft steel wires are used as reinforcing cores 1 and 2 in the power core conductors and control core conductors, and positive and negative Stranded, such conductors have high soft torsional stability, as well as excellent tensile, impact and bending resistance. In order to eliminate the electric field distortion on the surface of the conductive core, homogenize the electric field, and reduce the free discharge, a semi-conductive nylon tape is used as the conductor shield. Insulation 1 and insulation 2 use mixed ethylene-propylene rubber insulation with excellent electrical properties, ozone resistance, high heat resistance and mechanical properties. The combination of semi-conductive nylon tape and tinned copper wire braid is used for shielding. The semi-conductive nylon tape has good contact with the insulation, which can reduce the air gap and the free discharge generated, and homogenize the electric field; the metal braid outside the insulation, It has a certain tensile and ground wire protection effect on the insulation. Since this cable is a moving cable, there is a certain tension during operation, and sometimes leakage current may be generated due to certain factors. Therefore, tinned copper wire braided shielding can play a certain role in tensile resistance and can be reliably grounded to improve system performance. security. The outer sheath is subject to frequent bending, twisting, pulling, friction, and sunlight aging, etc., so the outer sheath material has excellent weather resistance, wear resistance and excellent mechanical strength, so butyl is used as raw material Silicone rubber compound as sheath material.

The beneficial effects and advantages of the utility model are: the use of soft steel wires as the reinforcement core 1 and reinforcement core 2 stranded power core conductors and control core conductors, compared with ordinary bucket wheel machine cables, its stability and tensile resistance are all enhanced , It fundamentally solves the conductor breaking phenomenon caused by the movement of the core, greatly improves the service life of the cable, and prolongs the replacement cycle of the cable. The semi-conductive nylon tape is used as the conductor shield, which homogenizes the electric field and reduces the impact damage caused by the free discharge to the insulation, and the service life of the cable insulation of the common bucket wheel machine is prolonged. Compared with the current one-layer shielding, the combination shielding of semi-conductive nylon tape and tinned copper wire enhances the tensile strength and improves the safety of the system and personnel. The butyl silicone rubber compound is used as the outer sheath, which is superior to ordinary rubber in terms of traction, wear resistance and aging. Combining the control wire cores, the comprehensive cost is relatively low, the installation is simple, and the construction cost is low.
