三、生产工艺

材料按生产计划选定材料工艺规定的标准尺寸后，按工艺尺寸经过下料、冲孔、弯曲、焊接等工艺加工完成，等待发货。

1、 Product introduction A hoop is a component that holds or hoops another material with one material. It is a fastener. The electric hoop device is composed of hoop plate, wing plate, tie bar plate, bolt and inner liner. There are many kinds of hoops, such as pole top support hoop, cable hoop, cross arm hoop, stay wire hoop, etc. Generally, the left and right half hoops are connected after closing. Both the left and right half hoops are semicircular, and the two ends of the semicircle ring are bent outward to form an installation ear. Bolt connection holes are punched on the installation ear, and the connection and installation are carried out with necking bolts. The main raw material is flat steel.

2、 Product selection The main material of the product is Q235 steel in GB / T 700-2008 standard, and the tensile strength of the material is ≥ 400MPa.

3、 Product classification

3.1 pole top support hoop The pole top support hoop is installed on the pole top, which is divided into single roof single holding, double top single holding, single roof double holding and double top double holding, which is used for 10kV and below lines. Single top single holding, double top single holding, single top double holding, double top double holding

3.2 stay wire hoop The stay wire hoop is used to fix the pole by pulling wire in the line, including flat holding, reinforced flat holding, double pulling wire holding hoop and four pulling wire holding hoop. Generally, the specification of flat steel and the diameter of the holding bar are used to express the specification, such as: - 60 × 6 × 150. Flat holding, reinforced flat holding, double pulling wire holding hoop and four pulling wire holding hoop

3.3 conductor hoop The wire hoop is divided into conductor wire hoop and wire stay hoop, which is used for hanging wire, conducting wire and pulling wire or at the same time. It is used for 110kV and below line project, and its specification is indicated by its own number according to each design. Hanging hoop, middle guide hoop, triple pole conductor hoop, triple pole wire stay hoop

3.4 bracket hoop and bracket stay wire hoop The supporting arm hoop and supporting arm stay wire hoop are used to support the cross arm or simultaneously support the cross arm and stay wire in 35kV and above power lines. The difference between the two is that the latter has more wire drawing boards than the former, and its specifications are indicated by the number determined by each design.

3.5 lifting hoop The hoop is used to lift the load. There are two connecting screw holes on one side of the hoop. Generally, each pair is connected with four sets of necking bolts. The specification is expressed by the specification of flat steel and the diameter of the position of the holding pole, such as - 80 × 8 × 280.

3.6 cable hoop The cable hoop is used to fix the cable when it is up and down the pole. According to the number of fixed cables, it can be divided into single cable hoop, double cable hoop and multi cable hoop. The main difference is that the cable hoop has different order of magnitude. Its specification is shown by the material specification and the diameter of the pole, for example: - 60 × 6 × 320. Single electric hoop and double cable hoop

3.7 brace hoop There are several kinds of bracing hoop, such as welding plate, welding bolt, flat holding to strengthen flat holding. The specification is expressed by the specification of raw materials and the diameter of the pole, such as: - 60 × 6 × 210.

3、 Production technology After selecting the standard size of material process according to the production plan, the material is processed by blanking, punching, bending, welding and other processes according to the process size, waiting for delivery.
