Abstract
The utility model provides a rigidity rubber insulation terminal for high -pressure flexible power cable, a serial communication port, including supporting strengthening rib, rubber outdoor termination, conductive terminal and support flange, rubber outdoor termination locate the high -pressure flexible power cable outside, the support strengthening rib locate in high -pressure flexible power cable's the sinle silk part, high -pressure flexible power cable's the sinle silk subtotal top of supporting the strengthening rib expose from the rubber outdoor termination and be fixed in conductive terminal in, high -pressure flexible power cable's bottom is fixed through supporting the flange. The utility model discloses the rigidity at terminal has been improved under the condition of not destroying insulation system for can use in the occasion that has very big wind -force load and vibration.
Description
Technical field
The utility model relates to a kind of hard rubber for high-voltage flexible power cable insulation terminal.
Background technology
Flexible cable power cable is generally used for and needs often mobile, pulls or have the occasion of the fixed installation position compared with small curvature radius, is used for transferring high voltage electric energy.The terminal of flexible cable then requires to have certain rigidity, causes creepage distance to shorten to prevent the deformation owing to crossing macrobending, and the insulation property reduction caused punctures the faults such as flashover.
Flexible power cable consists of the following components: 1. the flexible cable core of strand restrainted in the same way by thin tinned copper wire, 2. three-layer co-extruded elasticity EPR rubber-covered and interior out semiconductor layer, 3. proof copper-wire braided earth shield 4. rubber sheath.Existing take rubber as the cable termination main part of main material is two-layer, electric stress key-course and insulating barrier.Above cable and terminal are all flexible materials, do not play the parts of rigid support effect.Therefore this system out of doors, has the use of the occasion of wind load or vibration to be limited to.
Utility model content
The purpose of this utility model is to provide the rubber-covered terminal strengthened with rigidity, the basis not changing original insulation system and electrical property provides rigid support, makes this product having wind or to have the occasion of vibration normally to use.
In order to achieve the above object, the utility model provides a kind of hard rubber for high-voltage flexible power cable insulation terminal, it is characterized in that, comprise supporting rib stiffener, rubber outdoor terminal, conducting terminal and pivot flange, described rubber outdoor terminal is located at outside high-voltage flexible power cable, described supporting rib stiffener is located in the core part of high-voltage flexible power cable, the described core part of high-voltage flexible power cable and the top of supporting rib stiffener are exposed and are fixed in conducting terminal from rubber outdoor terminal, the bottom of high-voltage flexible power cable is fixed by pivot flange.
Preferably, described supporting rib stiffener is made up of main part, transition portion and bottom hemisphere portion, and described main part is cylindrical, and the diameter of bottom hemisphere portion is less than main part.
Preferably, the length L1 of described supporting rib stiffener is 600mm, and the length L2 of transition portion is 6mm, and the diameter of phi of main part is 4mm, and the radius R of bottom hemisphere portion is 1mm.
Preferably, the width W of described pivot flange is 60-80mm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model improves the rigidity of terminal when not destroying insulation system, making it possible to is having the occasion of very large wind load and vibration to use.
Accompanying drawing explanation
Fig. 1 is the hard rubber insulation terminal structure schematic diagram for high-voltage flexible power cable;
Fig. 2 is supporting rib stiffener structural representation.
In figure, 1 is supporting rib stiffener; 2 is rubber outdoor terminal (comprising electric stress control assembly), and 3 is conducting terminal, and 4 is pivot flange, and 11 is core part, and 12 is cable insulation, and 13 is cable sheath.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment
As shown in Figure 1, hard rubber for high-voltage flexible power cable insulation terminal of the present utility model, it is characterized in that, comprise supporting rib stiffener 1, rubber outdoor terminal 2, conducting terminal 3 and pivot flange 4, described rubber outdoor terminal 2 is located at outside high-voltage flexible power cable, described supporting rib stiffener 1 is made up of metal material, be located in the core part 11 of high-voltage flexible power cable, the external structure of the core part of high-voltage flexible power cable is all elastomeric material or establishment copper wire structure that pliability is very high, certain expansion deformation can be born and do not affect insulation property.
The core part of described high-voltage flexible power cable and the top of supporting rib stiffener 1 are exposed and are inserted in conducting terminal 3 from rubber outdoor terminal 2, are fixed by pressing mold extrusion process.The length of supporting rib stiffener 1 will be longer than rubber outdoor terminal 210mm, and the bottom of high-voltage flexible power cable is fixed by pivot flange 4.The width W of described pivot flange 4 is 80mm, adopts wide pivot flange 4, and high-voltage flexible power cable can be prevented in the bottom bend of supporting rib stiffener 1, and causes supporting rib stiffener destruction insulating barrier to cause the accidents such as electrical breakdown.
The diameter of supporting rib stiffener 1 is moderate, can either provide enough support strengths, can not cause again the deformation that the material such as cable insulation 12 and cable sheath 13 is excessive.As shown in Figure 2, described supporting rib stiffener 1 is made up of main part 21, transition portion 22 and bottom hemisphere portion 23, described main part 21 is cylindrical, the diameter of bottom hemisphere portion 23 is less than main part 21, the length L1 of supporting rib stiffener 1 is 600mm, the length L2 of transition portion 22 is 6mm, and the diameter of phi of main part 21 is 4mm, and the radius R of bottom hemisphere portion 23 is 1mm.The profile of described supporting rib stiffener 1 can reduce resistance when brace rod embeds cable core as far as possible, can avoid lesion wire core conductor again.
During installation, cable sheath 13 is normally divested according to the instruction for mounting of cable termination, metal screen layer, semiconductive shielding layer and cable insulation 12, aligning cable, supporting rib stiffener 1 is inserted into carefully in core part 11, flush with core part 11, install and fix pivot flange 4 and earth connection.Normal mounting terminal and crimp type terminal.
