10 kv crosslinked heat shrinkable cable accessories three core terminal head craft
10 kv crosslinked heat shrinkable cable accessories three core terminal head craft is how? In this article, heat shrinkable cable accessories professional manufacturer power of small make up to introduce to everyone, hope to be of help.
1。 Cutting kai packed layer
50 mm (outer sheath incision in To paint) With a copper cable tie binding, after the rest of the strip. Note shall not exceed the kai two-thirds of thickness, cutting depth of incision should be flush, there should be no sharp corners and sharp edges, don't hurt while cutting the inner structure.
2。 Cutting lining layer and the filler
since kai to incision in 20 mm lining layer, the rest and the filler strip. Do not hurt the copper shield.
3。 Installation of ground wire
the ground wire with copper cable tie tied tightly in every phase of copper shield and to paint on steel kai, and weld. Attention to plunge into silk of not less than 3, welding surface not less than 1/3 of the circumference of a circle, solder joint and the firm should handle the flat wire head, there should be no sharp corners, burrs. Ground wire sealing section should do moistureproof processing, Permeability of tin or winding and sealant) 。
4。 Around the bag filling glue
with filling glue around the bag filling cable branch root gap and lining layer exposed part of the sag, and olive shape, diameter slightly larger than cable ontology. Clean up in the ground and in the direction of the cable outer sheath slit winding and a layer of sealant 30 mm wide.
5。 Fixed finger
tries to set set to fixed line core roots after heating, to shrink the roots, then shrink sleeve and fingers. Pay attention to the flame heating in the direction of the contraction, soft hard moderate and constantly rotating and moving.
6。 Cutting copper shield
the amount refers to the set of end take 50 mm copper shield, with poly (ethylene from drill with the rest of the copper shield off after temporary fixed. Pay attention to the heat shrinkable cable accessories incision should be flush, there shall not be sharp corners.
7。 Cutting outer semiconductive layer
according to the size of heat shrinkable cable accessories, retained copper shield incision semi-conducting layer within 20 mm. The rest of the strip. Pay attention to the incision should be flush, leaving no remnants ( Use detergent to clean insulating layer surface) , do not hurt the main insulation layer.
8。 Fixed the stress control tube
temporary fixed tape stripping, lap copper shield 20 mm, and from that point on fixed heating. Note heating flame in the direction of the contraction, soft hard moderate and constantly rotating, moving.
9。 Stripping the insulation layer
online core end to remove terminal hole depth and the main insulation layer of 5 mm. Pay attention to conducting wire core shall not be hurt.
10。 Cutting cone reaction force
independent measuring insulation fracture place 40 mm, cut into 35 mm cone, keep 5 mm inner semiconductive layer, demand cone round.
11。 Crimping terminal
each terminal pressure 2. Note after pressure to the cutting edges, burrs should be removed.
12。 Winding and sealant
in the reaction force of cone surrounding the sealant ( Or J - 20 rubber insulated from a cat) And lap terminal 10 mm. Pay attention to around the cladding shall be continuous and smooth surface.
13。 Fixed insulating tube
will be insulated pipe sleeve to three prong roots ( Tube top beyond filling glue 10 mm) And start from the roots of heat shrink. Note heating flame in the direction of the contraction, soft hard moderate and constantly rotating, moving.
14。 Fixed seal tube
to seal pipe sleeve to terminal and the insulating joint, preheating terminal first, starting from the terminal side heat shrink again. Pay attention to the seal should be grinding and plastic bags in advance.
15 stationary phase color tube
group color tube set on the sealing tube, heating fixed indoor installation.
