1. The process of making indoor terminal head with heat shrinkable 10KV cross-linked cable?

(1) Preparation stage: check whether the heat shrinkable cable accessories are complete and whether the models match. After checking and confirming that the cables are free of moisture, check the cables; (2) Cut off excess cables and determine the cable length based on site conditions; (3) Peel off the protective layer; (4) Weld the ground wire onto the steel strip; (5) Filling the three prongs and wrapping sealant; (6) Install the three-core branch sheath, insert the sheath into the root, shrink from the middle, first towards the root, then towards the finger; (7) Peel the copper tape and the outer semi conductive layer, peel and cut the copper tape with a diameter of 20mm or more from the three-core branch socket. It is strictly prohibited to damage the main insulation, and clean the semi conductive layer; (8) Install the stress tube, and heat shrink the part of the support sleeve at the nozzle end after butt joint; (9) Install wiring terminals; (10) Install insulating pipes; (11) Install the sealing pipe; (12) Install a phase color tube after phase verification.

2. What are the installation steps for indoor and outdoor prefabricated terminals?

(1) Place the cable in place according to the predetermined position, fix it, and clean the surface. Refer to the instructions to peel off the outer sheath. If there is special need, the peeling length of the outer sheath can be adjusted, and two sets of ground wires are respectively led out from the copper tape and the outer sheath armor；(2) Measure the required size upward from the outer sheath opening, cut off the excess cable, insert a heat shrinkable three finger sleeve until the root of the three prongs is heated and contracted in the middle, and measure the specified size upward from the upper opening of the finger sleeve (350~380mm for 35kV). Remove the excess copper tape (keep 20mm), then reserve the predetermined position of the semiconductor, and crimp the outlet terminal for sealing.

3. What are the three main categories of wire and cable applications?

1. Power system. The main wire and cable products used in the power system include overhead bare wires, bus bars (buses), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables), branch cables (replacing some buses), electromagnetic wires, and electrical equipment wires and cables for power equipment; 2. Information transmission system. The wires and cables used for information transmission systems mainly include local telephone cables, television cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic cables, power communication cables, or other composite cables; 3. Mechanical equipment, instrumentation systems. Almost all products except overhead bare wires are used in this section, but mainly power cables, electromagnetic cables, data cables, instrument cables, etc.
