Scope: This document specifies the terms and definitions, technical requirements, test methods, factory inspection, and packaging requirements for the supporting and connecting components involved in the construction of strong steel wire electric fences for pastures. This document applies to the requirements for supporting and connecting components in the construction of permanent strong steel wire electric fences for pastures. Main technical content: 4. Guidelines: All supporting and connecting components and their structures should meet the needs of electric fence construction for pastures, and be able to operate safely during normal use. Even if there may be possible negligence during normal use, they should not pose a danger to personnel and the surrounding environment. Generally, the above-mentioned guidelines are achieved through the various relevant requirements specified in this section. 5. Requirements 5.1 Supporting components 5.1.1 Load-bearing columns (stress-bearing columns) include end columns, corner columns, and gate columns. Materials and specifications are referred to in the appendix. 5.1.2 Intermediate columns: Materials and specifications are referred to in the appendix. 5.1.3 Supporting columns: The length of the supporting columns buried in the ground should not be less than that of the load-bearing columns. Generally, they should be made of the same material as the load-bearing columns. 5.1.4 Anchors: Generally, steel wire + tensioner or reinforcing bar + tensioner is used as the anchor rope (precast steel parts), and round logs, cement, and angle steel are used as the anchor points. Materials and specifications are referred to in the appendix. 5.2 Connecting components 5.2.1 Insulators should be oxidation-resistant and corrosion-resistant, and able to withstand a test voltage of not less than 10 kV. 5.2.2 The insulating layer of double-insulated high-voltage conductors should be able to withstand a test voltage of not less than 10 kV inter
