Pay Attention To The Installation Line Of The Nylon Cable Connector When Wiring

There are many ways to check the phase of the cable line. At present, the more common and convenient method is to use the dry battery and voltmeter method. Pay attention to the installation line of the nylon cable connector when wiring to avoid cross connection. After the nylon cable connector confirms the phase of terminal A, connect the positive lead of the dry battery box to the A phase terminal and the negative lead to the B phase terminal, and then use the dial core at terminal B to indicate zero crossing. The DC voltmeter with a suitable measuring range can find the corresponding voltage. The two cores are phase A and phase B respectively, and the third phase generally does not need to be checked again.
(1) When two power sources are connected through a cable line. Phase mismatch will result in the inability to close the loop and affect the normal operation of the cable connector.
(2) When the nylon cable connector cable line supplies power to users, the two-phase phase error will reverse the running user's motor. The three-phase connection will cause users to use dual power supplies and cannot use dual power supplies at the same time. For users who only need one power supply, when they apply for backup power, they will not be spared.
(3) When power is transmitted from the cable line to the grid transformer, the low-voltage grid cannot be shut down and run in parallel.
(4) When two or more cables are running in parallel, if the phase of one of the cables is connected in the wrong way, it will have the adverse effect of not being able to push the switch.
Nylon cable joint made into heat shrink tube type cable gland
We first strip and cut the nylon cable joint. The purpose is to prevent the total outer diameter of the joint from being too large or too small, and to ensure that the size distance is appropriate, the connection of each phase core can be staggered, and the length of the stripped core of each phase should take into account the bending requirements of the core (for the convenience of curling the connecting tube) and the pre-inserted heat shrink tube of each phase core (the length of the tube should not be less than the length of the wire connecting tube plus 100mm).
The cable covers the heat shrink outer sheath of the connector at one end of the cable, passes through the waterproof connector of the cable, and then sets a small heat shrink tube on each wire core on the long end of the wire core, and then crimps the wire connecting tube.
Nylon Cable Gland is wrapped with insulating rubber self-adhesive tape. It is different from the waterproof joint. Start about 30mm from the insulation at one end of the wire core, and continuously wrap it through the wire connecting tube to the same position at the other end of the wire core insulation. The pressure pit on the top and the gaps at both ends are filled, and then wrapped with 3-5 layers.
