Brief description of the operation requirements of glass fiber insulated tubes
Insulating bar: also known as gram bar, insulated rod, operating rod, etc. The insulating rod is composed of a working head, an insulating rod and a grip. It is used when closing or pulling high voltage disconnectors, attaching and detaching portable grounding wires, and performing measurements and tests. The insulating rod is also called the gram rod.
Insulation rod operation requirements
1. In order to ensure sufficient insulation safety distance during operation, the length of the insulation part of the insulated operating rod shall not be less than 0.7m;
2. It is required to have high compressive strength, corrosion resistance, moisture resistance, high mechanical strength, light weight and easy to carry, and one person can operate alone;
3. The connection between the three sections should be firm and *not allowed to fall off during operation.
A pair of insulating rods generally consists of three sections. When storing or carrying, the sections should be disassembled and then put into the special special tool bag with the exposed thread end facing up to prevent the surface of the rod from being scratched or the thread is damaged.
Insulation bar storage method;
1. A pair of insulating rods generally consists of three sections. When storing or carrying, the sections should be disassembled and then put into the special special tool bag with the exposed thread end facing up to prevent the surface of the rod from being scratched or the thread is damaged.
2. When storing, choose a well-ventilated, clean and dry place, and hang the space on the special brake bar frame, which is managed by a special person. The insulation plate should not be in contact with the wall to protect it from moisture.
3. Once the surface of the insulating rod is damaged or damp, it should be treated and dried in time. The surface damage of the rod should not be wrapped with a ribbon such as a wire or a plastic strip. When drying, it is best to use the natural drying method of sunlight. After treatment and drying, the brake rod must pass the test before it can be reused.
4. An AC withstand voltage test must be carried out every year. Insulation rods that fail the test shall be immediately scrapped and destroyed, and shall not be used in standard use, and shall not be placed together with qualified insulating rods.
