Fujian sales of high voltage 110KV ground wire

line cards and other main parts are made of aluminum alloy pressure casting, and the line cards are durable. , easy to operate, especially the spring-loaded type, just hang and pull on the wire.
Reasonable supporting facilities and reliable functions. According to the voltage level, the grounding wire should be selected reasonably. The line card has a simple structure and a large contact surface with the wire.
The line card has a wide practical range and can adapt to the needs of different wire cross-sections.
2. Practical scope:
Ambient temperature: The ambient temperature during normal use is +. In special climatic conditions, the manufacturer's supervision unit and the user will jointly negotiate and customize.
. Scope of application: This product is divided into two categories: split-phase type and combined type. Line cards are divided into two categories: spring-pressed type and spiral type. Among them, the screw-pressed flat-mouth line card is suitable for power outage maintenance in copper and aluminum busbars and indoor switch cabinets, and the spring-pressed alligator type (E-mouth line card) is suitable for power outage maintenance on kilovolt lines. The remaining line card interface diameters adapt to the grounding needs of wires with different rated short-circuit currents to ensure personal safety during maintenance.
3. How to use:
Split-phase type: There are three groups of grounding wires in each set. Each group is connected by a wire end line card, a short-circuit line and a grounding end line card. Group operations when used. Check the electricity first according to the regulations. After confirming that there is a power outage, first fasten the ground terminal line card to the ground electrode, then select the operating rod according to the voltage level of the power outage line, and hang the wire end line card on the conductor. After the work is completed, the wire terminal line card should be removed first, and then the ground terminal line card should be removed.
Classification of ground wires: The specific configurations of ground wires are different under different voltage levels and different use environments. The specific configurations of ground wires under the same voltage level and different use environments are also different (the length of the ground rod, the length of the ground rod, the The style of the electric clamp, the thickness, length, grounding method, etc. of the grounding soft copper wire). Therefore, when purchasing a ground wire, users must understand the specific usage environment and accurate voltage level in order to make the correct selection.
The grounding wire on the cable joint in the high-voltage distribution box is a protective ground. Its function is to pass the high induced voltage on the outer shielding layer of the cable joint and the leakage current generated when the cable joint fails through the grounding wire and then through the grounding system. Introduced into the earth to ensure the personal safety of equipment and staff. Since this cable joint is a relatively new cable connection technology in China, the construction and maintenance departments have insufficient experience. At the same time, due to the tight schedule, heavy tasks, and lagging management of urban network reconstruction, some high-voltage distribution boxes have been damaged after being put into operation. The ground wire on the cable connector inside does not meet the technical requirements.
