Standard for Installation of Pole Cable
The installation standard of electric pole stay wire includes the following points: 1. The stay wire is generally made of multi-stranded galvanized steel wire with the specification of GJ-35 ~ 100;2. The connection fittings of stay wire are generally made of wedge clamp and UT clamp; 3. When making stay wire, the upper and lower steel strands are cut off respectively after the required length is calculated and determined, and both ends of the upper and lower levers and the connection end of suspension insulator are fixed and bound by wedge clamp; 4. The binding length of the back end of the pull wire is 8-10cm, and the end retention head is 3-5cm;5. The cross section of the pull wire should correspond to the cross section of the pulled wire, and its strength design safety factor should not be less than 2 and the specification should not be less than 35mm2;6. The diameter of the pull rod should not be less than 16mm, and the pull plate should not be less than 40cm × 60cm;7; 8. The windproof cable is used to balance the horizontal wind, and it is decided whether to install the windproof cable according to the actual situation of the climate and geographical location of the region.
According to the breaking current range, the fuse can be divided into general-purpose fuse, backup fuse and full range fuse. General-purpose fuses are mainly used to protect power transformers and general electrical equipment, while backup fuses are often used in series with contactors to protect motors. The rated voltage of the fuse should be consistent with the operating voltage of the motor, and the operating voltage is related to the length of the fuse tube. The material, cross-sectional area and temperature rise of the connecting line shall also comply with the regulations and shall not be changed at will. In addition, the dust accumulated on the fuse should be removed in time, and the fuse with an action indicator should be checked regularly, and the fuse should be replaced in time if it is found to have acted.
Function of Circuit Breaker on Pillar
The circuit breaker on the pole is a kind of electrical equipment used to cut off and connect the circuit, which is mainly used in the power system. Its functions include: protecting the components in the circuit from damage due to faults such as overcurrent or short circuit; providing safe circuit control functions, such as disconnecting or connecting the power supply; and performing isolation operations in the circuit to avoid circuit failures. Fire or other hazards. In addition, the circuit breaker on the pole also has the characteristics of long life, high performance and high reliability.
