There are many kinds of indoor cable heads, including indoor dry pack type, heat shrink type, paper insulation cast type and so on. However, the general low-voltage power distribution project uses dry bales and heat shrinks.
Dry bag type: the material is only used high-pressure tape, color tape, plastic tape, terminals, etc., with artificial direct winding, no additional protection on the cable core.
Heat-shrinkable terminal heads: plastic gloves, plastic heat-shrinkable tubes, phase tubes, terminal blocks, etc., all of which are heat-shrinkable with alcohol torches. First shrink the tube, then shrink the gloves, the phase tube, and the crimp terminal. Different from the dry bag type, the thermal protection method has a relatively high level of protection. The core wire is protected by a layer of plastic tube. It is also relatively beautiful. Of course, the price is much higher. 70-square-gloves will probably have dozens of pieces. Money. The construction organization design is compiled after entering the field. Party A and the design have requirements for cable heads as required. Those who do not require can choose their own practices.
In practice, there is no pre-branch cable head. The pre-branch cable is a finished product. It is processed by the manufacturer according to the height of the storey and the length of the branch. It can be lifted directly to the site, and its cable head is the same as the ordinary cable head. difference. The head of the cable branch is not processed on site and it cannot be processed on site. The second floor is wrong, so only use the T terminal box or puncture clips.
Dry bale type cable heads are generally used in low voltage cable heads and are wrapped in insulated plastic tape for dry bale heads. Pouring cable heads are generally used in high-voltage cable heads. He is a cast cable head that is formed by sourcing the finished product molds and filling the insulating glue after installation. Heat-shrinkable cable heads are generally used in high and low voltage cable heads, he is used to purchase finished heat-shrinkable tubes and heat-shrinkable gloves, gradually installed in place with a blowtorch heat shrinkable tube and heat shrinkable gloves, heat shrinkable tube and heat When the shrinkage gloves see heat, they will shrink the formed cable head.
