Plastic and rubber insulation terminal head production technology
plastic and rubber insulation terminal head production process how? I believe many people will have this problem, AnWei electric power company of small make up today for everyone to reassure:
( 1) Process to prepare
1) selection and ready to branch or gloves. According to the installation of cable specifications. Three core cable with three core branch of glove specification size, structure, shape and scope of application in four core cable with four core branch glove specification size, structure, shape and scope of application.
(2) to choose a good cover.
(3) technology and construction preparation. Cable terminal, branch gloves for inspection, check the terminal head and phase sequence of the cable, the cable fixed well.
(4) tool mould ready. Soldering iron, latex gloves and common electrician tools, box of ruler, a ruler.
5. Auxiliary materials preparation. Prepare PVC glue a belt; Semiconductor butyl tape for shielding, the specification is 0. 25mm X 30mm; Shielding the aluminum foil strip specification for ( 0. 09 - 0. 1) mmX ( 25 ^ - 30) mm; # 1 - used as shield ring 2 mm soft lead wire; Specification is 19/0. 28 tin plated copper wire for ground wire; Specifications for ( ( 7/0. 25) Tied the copper wire; In addition to solder, acid free rosin flux, etc.
( 2) Under 10 kv cable termination process operation procedures and process
under 10 kv plastics and rubber insulated power cable terminal points and 10 process production process, as shown in figure 3 - cable termination structure 68. The detailed operating procedures according to table 3 - 36, the content of cutting process structure size.
( 3) 3 kv and 0. Requirements of making the 5 kv cable termination
1. Level 3 kv. Requirements and net distance, outdoor is 200 mm, indoor type is 75 mm; Intermediate core covering a length of 400 mm, but the length does not include the plug hole copper joint part, the rest of the two phase according to the process should be appropriately increased; When installed people outdoors, need to add cover, for a grade 3 kv cable because it had no shielding layer, so the construction does not need to install the stress cone.
②0。 Level 5 kv. 0. 5 kv cable termination when its production and net distance, outdoor is 120 mm, indoor type is 75 mm; Intermediate core covering a length of 200 mm, also does not include the plug copper joint hole part; Appropriately increase the rest two phase according to the process, to 0. 5 kv level regardless of terminal installed in indoor or outdoor, have not been to cover, and because of cable shielding layer, also do not need to put stress cone.
have been cautious, try to do better. If there is any question, welcome to inquire AnWei electric power company. 24 hours service hotline:
