Embodiment 1
[0029] Such as figure 1 As shown, the tubular busbar provided by the present invention has a cross-sectional structure from the inside to the outside by combining the metal pipe conductor 1, the conductor shielding layer 2, the insulating layer 3, the insulating shielding layer 4, the metal shielding layer 5, and the closed jacket 6. into, and the above-mentioned structural layers are bent synchronously. There are various specifications for bending radius and curvature to meet the needs of different occasions.
[0030] The above-mentioned structure of each layer of the cross-section of the present invention adopts solid insulating materials, such as silicone rubber, ethylene-propylene rubber and cross-linked polyethylene, etc., to coat the conductive tube through processes such as extrusion and molding, and to form a conductive tube with vulcanization or cross-linking. Tubes are firmly bonded together as one integral insulating layer to meet insulation, weather resistance, be...
Embodiment 2
[0033] Such as figure 2 Shown is the layout of the special processing device for the tubular busbar of the present invention. A three-layer co-extruded extruder head 7 is placed in the central part, and two sections of brackets 8 are arranged on the longitudinal side of the extruder head, and a tractor 9 is arranged between them. Obviously, the tractor acts on the drawbar 10 . A track 11 and a vulcanization channel 13 are arranged on the other longitudinal side of the extruder head, and a rail car 12 is arranged on the track. Perpendicular to the above arrangement direction, insulating layer extruders 14 and insulating shielding layer extruders 15 are arranged symmetrically on both lateral sides of the extruder head, and conductor shielding layer extruders 16 are also arranged on either side. The outlets of the above-mentioned insulation layer extruder, insulation shielding layer extruder and conductor shielding layer extruder are all connected to the extruder head.
Embodiment 3
[0035] A copper tube is selected as the metal tube conductor, with an outer diameter of 120 mm, a tube wall thickness of 13 mm, and a tube length of 6000 mm.
[0036] Use polishing equipment to process the surface tip, and use a cleaning machine to clean the copper pipe to remove the dust on the surface. After cleaning, apply a coupling agent on the surface of the copper tube, such as TH-101H, TH-106, etc.
[0037] Choose 100 parts of EPDM solid material, add vulcanizing agent materials, such as sulfur, DTDM, 1 part; zinc oxide, 5 parts; accelerators, such as PZ, DTDM, 1.5 parts; calcium carbonate, 55 parts; oil, such as No. 34 cylinder Oil, No. 38 cylinder oil, 10 parts, 1 part of stearic acid.
[0038] Firstly, pull the EPDM rubber on the open mill for 4 times (the roller distance is below 0.4mm), cool it a little after unloading, and then enlarge the roller distance a little, and put the masticated EPDM rubber or silicon Add rubber and make it cover the rollers. At the sa...
