The main function of the PH extension ring is to provide additional support and protection to ensure the stable operation of the wire line. It plays an important role in the power system, especially in the need to withstand large tensile occasions.

Installation method of Extend the ring

When installing PH extension rings, it is necessary to strictly follow the construction standards of the State grid. First, you need to determine the installation location and then fix it. During the installation, keep the installation firm to prevent loosening or falling off.

PH extension ring specifications and size data

PH extension rings are available in a variety of sizes, including PH-7D, PH-10D, PH-12, PH-16D, PH-21D, PH-25D and PH-30D. Each type of PH extension ring has its specific size data and weight to meet the needs of different occasions

Extension ring PH-7 is a kind of connection fittings for power system, mainly used for hanging and fixing wires, insulators and other equipment. It is fixed with the pole and tower crossarm by bolted connection, so that the crossarm structure can be simplified

definition

Extension ring PH-7 is a U-shaped screw used for power system, which belongs to a kind of connecting fittings, mainly used for hanging and fixing wires, insulators and other equipment

effect

Extension ring PH-7 is mainly used to connect and fix wires, insulators and other equipment in the power system to ensure the stable operation of the power line. Specific roles include:

Suspension of suspended insulator strings

Fixing of the overhang combination of lightning arrester

First piece of pole and tower crossarm connection

material

The material of the extension ring PH-7 is usually Q235 steel or 316 stainless steel, and the surface treatment is mostly hot-dip galvanized to improve its corrosion resistance.

Usage

The extension ring PH-7 is fixed with the pole and tower crossarm by bolted connection, which simplifies the crossarm structure. It is usually used in linear pole tower suspension suspension insulator string, lightning rod suspension combination and other scenes.

Installation method

The installation method of PH extension rings usually includes the following steps:

Prepare tools and materials: Ensure that all necessary tools and materials are available, including bolts, nuts, and washers.

Check the equipment: Check that the extension ring PH-7 and its connecting parts are in good condition and ensure that there is no rust or other defects.

Installation connection: Connect the extension ring PH-7 to the pole and tower crossarm, and fix it with bolts, nuts and washers to ensure a firm connection.

Adjust position: Adjust the position of the extension ring PH-7 as needed to ensure that it is connected correctly with other equipment.

Check fastening: After the installation is complete, check whether all the connection parts are tight to ensure that there is no loosening.
