How to choose a dielectric stepladder?
Fiberglass ladders are distinguished by their modern design and ease of use. Working with electrical appliances and electricity in general is dangerous to human life and health. To prevent unfavorable situations, it is necessary to use special means aimed at protecting against the effects of electric current. The dielectric ladder is considered a modern tool for such work.
Features of Fiberglass Fiberglass Stepladder
A stepladder is required for workers who carry out their work on a hill. Aluminum and steel structures are dangerous for electrical work, as well as for repairing electrical wiring and replacing light bulbs.
It should be noted that even special protective equipment (eg workwear and tools with insulated handles) is often insufficient. Fiberglass ladders help to reduce, as well as to exclude possible electric shock.
Fiberglass or fiberglass is based on a fibrous filler. It consists of threads, flagella, and tissue. All thermoplastic polymers bind it together. These include various types of resins such as polyester, vinylester, and epoxy types. This is an expensive material for production; accordingly, the prices for fiberglass stairs are higher than for metal structures. Such ladders come in 3 steps, but models with 5 or 7 steps are popular.
The thermal conductivity of plastic is low, therefore, in terms of characteristics, it is closer to wood. Plastic does not allow hands to freeze, does not heat up in the heat. Thermal conductivity can be the same for wood and fiberglass, but according to other criteria, fiberglass is definitely better. A number of advantages: stronger, mold does not start in the material, insects do not appear. The material does not rot.
Fiberglass is heavier than aluminum structures, but lighter than steel ones. Fiberglass ladders are easy to transport. Professional ladders reach a height of 3 meters, their weight is 10 kilograms.
In terms of strength, the fiberglass component is slightly inferior to steel. Of course, the absolute strength of steel exceeds that of fiberglass. However, fiberglass has low weight and specific strength. Its characteristics have more advantages than steel.
Another advantage of plastic is that it cannot corrode. Fiberglass stairs can last more than 20 years. She calmly withstands rainy weather, heat and severe frosts.
Insulating dielectric model
Fiberglass differs from others in its dielectric properties. Ladders made of aluminum and steel cannot guarantee such electrical safety.
Fiberglass structures are tested using a voltage of about ten kilovolts. One of the important qualities of fiberglass is its intrinsic safety. The stepladder does not ignite from sparks that fly out of the grinder when welding is being carried out.
Rubber foot pads ensure safe work on dielectric stepladders. High-quality fasteners also affect the choice of design, they give reliability to such stairs.
Many of these ladders have latches that prevent unintentional opening.
These ladders are designed for the following types of work:
- troubleshooting in everyday life;
- connection and maintenance of various electrical appliances;
- work at height;
- work under power cables;
- for work in rooms with electrical wiring on the floor without voltage.
Stepladder selection
When choosing this design, we first determine the height of the desired product. This is due to what actions will be performed in the future. There is a lineup in which it is not recommended to get up on the top step, as you can easily lose your balance. It is better to choose wide steps of the ladder, designed for comfortable work on them.
For works with a height of more than four meters, ladders with scaffolds are used. They have wide top areas and special fences. This makes it possible to safely perform work at height.
The corrugation on the steps is considered mandatory. Deep grooves have a sharp edge design, thus providing a comfortable grip for the shoe. For corrugation, abrasive chips and an aluminum profile are used.
The wheels for transporting the structure make it possible to move the ladder faster and more conveniently. Some models even have soft ground tips.
Preference should be given to ladders with a tray designed specifically for storing various types of electrician's tools.
The main key features of quality stepladders include:
- stability of the structure with symmetrical support;
- high-quality and efficient assembly;
- convenient operation and safe use and storage;
- mobility in use.
The following materials are used for the manufacture of stairs: steel, aluminum, plastic, wood.
Stepladders are one-sided, two- and even three-sided, but they are more common in production.
When buying, you need to pay attention to the following details.
- Platform height Is the length between the support and the top step. Each model has its own distance. It is important to clearly understand for what needs you are using this item: for home or in industry.
- Steps, their number: the shorter the distance, as well as the more steps, the more comfortable it is to use the ladder.
- Work load shows what maximum weight the top step can withstand without risking the stability of the ladder itself.
- Availability of additional useful tools for comfortable and mobile work, for example, the presence of wheels, a block for various tools, as well as a hook for a bucket.
