Abstract
The method include following steps: remove insulating sheath; make connection; place die sleeve of connector; make casting and solidify. The above die sleeve above is a hollow shell and is a bisect structure. Hole for main cable and at least one hole for branch cable are located on the shell. Pouring opening for injecting polyurethane insulating liquor is mounted on the shell. The invention adopts cold molding process that features low resistance and high reliability.
Description
Technical field
The invention belongs to field of cables, specifically refer to a kind of method and joint die sleeve that is applicable to the field fabrication branch cable joint that uses in the job site.
Background technology
At present, the branch cable of high request all is prefabricated in the factory, before making, must measure the size of main cable, branch cable, branch junction, but in the actual installation process deviation takes place, prefabricated branch cable is difficult to correct, in order to satisfy the needs of installing, usually be the length of amplifying cable, to bringing very big waste on the engineering.
Summary of the invention
The objective of the invention is problem, propose a kind ofly can be applicable to the method and the joint die sleeve of field fabrication branch cable joint according to the needs in the site operation at above-mentioned existence.
Technical scheme of the present invention is: the method for field fabrication branch cable joint of the present invention is made by following technical process:
(1) removes insulating sleeve: need the place of branch and the end of branch cable to remove insulating sleeve at main cable;
(2) connect: main cable and branch cable are fixed with retainer plate, with the crimping tool connection of colding pressing;
(3) place the joint die sleeve: place the joint die sleeve in the joint;
(4) cast cured explosive: after polyurethane insulating liquid and curing agent mixing, in the fill nipple die sleeve, final and joint die sleeve is cured as one.
Above-mentioned joint die sleeve is a hollow housing, for to opening structure, the hole of tandem arrangement main cable is arranged on the housing, and there is the sprue gate of cast polyurethane dielectric in the hole of at least more than one tandem arrangement branch cable on the housing.
The method of field fabrication branch cable joint of the present invention and joint die sleeve, owing to adopt the technology of colding pressing, contact resistance is little, power supply reliability is high.The insulation at the branch cable joint place of field fabrication is owing to adopt polyurethane resin, humidity, corrosion-resistant, high leakproofness.Therefore, have the advantages that the present invention makes things convenient for material-saving.
Description of drawings
Fig. 1 is the method for field fabrication branch cable joint of the present invention and the structural representation of joint die sleeve.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the expanded view of joint die sleeve of the present invention.
Embodiment
The invention will be further described by embodiment below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, need the place of branch and the end of branch cable 4 to remove insulating sleeve at main cable 2, fixing main cable 2 with branch cable 4 usefulness C type retainer plates 1, adopt the crimping tool connection of colding pressing, place joint die sleeve 5 in the joint, after 54HY polyurethane insulating liquid and curing agent (production of Changshu City, Jiangsu Province chemical industry insulating material factory) mixing, in the 6 fill nipple die sleeves 5 of sprue gate, final and joint die sleeve 5 is cured as one.
As shown in Figure 3, joint die sleeve 5 is hollow housing, for to opening structure, the hole 7 of tandem arrangement main cable and the hole 8 of a tandem arrangement branch cable is arranged on the housing, and the sprue gate 6 of cast polyurethane dielectric is arranged on the housing.
Claims (2)
