Not in all cases, telecommunication equipment, all kinds of meters can be installed in an apartment or house. Often such equipment is installed in the open air, which leads to the need for specialized products. Such a design is an all-weather electric street cabinet in which similar equipment is located.

Purpose and characteristics

Electrical cabinets for outdoor installation are non-standard configuration products made of materials with high resistance to wear. They are used for industrial purposes and in everyday life.Such a product is relevant for installation inside a power or lighting complex at administrative, commercial, agricultural, industrial facilities, as well as in private cottages and city apartments for switching networks with a voltage rating of up to 1000 V.

Inside this cabinet, optimal conditions are created for the operation of electrical equipment, since it has special openings for ventilation. Also, to establish a normal mode of operation of electrical appliances inside the cabinet allows good thermal insulation of its walls, for the organization of which innovative materials are used. Since overheating is not allowed, the power unit and the cabinet itself last longer.

What ensures the strength of the models, which serves as the basis for their long service life and high functionality? In the manufacture of such products, innovative materials are used (metal, plastic), which are coated with a high-strength composition.

Mount on a vertical surface of the product using universal fasteners. This allows you to reliably protect the contents of the structure from the negative effects of environmental factors: rain, wind, sunlight, insects. Also, the equipment inside such a cabinet will be provided with reliable protection against access by unauthorized persons, since many models have locking mechanisms of good quality.

Types and Features

Today on sale you can find several types of such devices.

Based on the installation method, street cabinets for electrical equipment are:

• built-in - they are flush mounted in a niche, therefore they can become part of the wall surface, completely hiding the internal contents from prying eyes;
• overhead - close the electrical equipment from the outside.

Recessed

Overhead

Based on the presence or absence of the stand, cabinets are:

• on a stand made of metal or other materials. Pretty reliable products that do not need to be additionally fixed to the wall;
• floor - are installed directly on the ground or a coating of concrete, brick, other materials;
• suspended - mounted directly on a pole, wall using special fasteners.

Floor

Suspension

On the stand

Based on the design features, the boxes are distinguished:

• open - the design has no doors, so its contents remain in sight;
• hidden - after installation, products of such a plan remain invisible to the eyes. When choosing such a product, its design is absolutely not important.

Based on the ability to disassemble the design, you can choose the model:

• one-piece - the construction is sold assembled without the possibility of disassembling it for parts. The case of such structures is cast;
• collapsible - manufacturers provide the user with the ability to assemble and disassemble the product if necessary.

Such products can have one, two, three compartments, which affects their capacity and functionality.

Characteristics and parameters

Models of dielectric cabinets have accompanying documentation that describes the main parameters specific to a particular model. It is thanks to this document that you can understand which factors can negatively affect the product, and which are not able to lead to its rapid wear.

The first parameter that must be taken into account is the degree of protection. Most of these products with a degree of protection IP31 protect the equipment from vertical droplets and foreign objects with a diameter of 2.5 mm. The IP54 degree of protection is absolutely resistant to moisture, dust, sudden drops or rising air temperatures. They are not afraid of precipitation, mechanical stress. They allow you to hide expensive equipment from prying eyes, protect it from the effects of weather conditions.

There are different indicators of impact resistance of the body of products, so the consumer can choose the product with the highest rates for expensive equipment.

Many models of boxes for electrical appliances that allow you to record electricity, have a special transparent window. Thanks to this design, you can take readings without opening the box. In any case, the internal contents of the electrical cabinet require careful attention. This will extend the life of the electronics.

Dimensions and nuances of accommodation

Based on what devices will be placed in the box, you can choose models of different heights, widths, depths. These parameters will determine the size, number of countable, power electrical elements that will fit inside the structure. The following table describes the standard sizes of floor and wall electrical cabinets for outdoor equipment.

When placing the selected model, it is important to take into account its parameters so that it successfully fits into the surrounding exterior.Built-in models are made to order based on pre-made measurements of the space where they are planned to be installed. Therefore, the place of future installation is carefully measured.

When placing ready-made cabinets with a standard configuration, it is important to take into account the fact that enough space is required to open the door. Also, additional space is occupied by visors, stand legs and other additional elements of a street cabinet.

Primary requirements

The basic requirements for an all-weather outdoor electric cabinet are as follows:

• durability - street cabinets are selected to protect electrical equipment, so they must certainly be of high quality. This means that the materials used in the manufacturing process (steel, stainless steel, polyester plastic) must demonstrate high resistance to wear during operation. This will make a reliable guarantee of the durability of the cabinet and the safety of the equipment inside it;
• safety - in the manufacture of such products metal, plastic are used, which should not contain harmful components, radioactive substances that can cause a strong allergic reaction in humans;
• ability to protect model contents. Thanks to the locking mechanisms, outdoor cabinets can restrict outsiders' access to internal contents. Models can be equipped with classic locks, a locking handle, a handle with a locking mechanism, a metal cam, an innovative locking system, a locking mechanism with a push latch;
• the presence of additional parameters - if the operation of the equipment inside the cabinet requires monitoring at night, it is important that the design is supplemented by lighting, sound signals. These parameters increase the cost of the product, which is important to remember when choosing it;
• effective thermal insulation of cabinet walls. This parameter will allow the electrical equipment not to overheat during operation, thereby providing the equipment a longer service life.
• design - for a street product this parameter is not so important, but it should be taken into account if it is placed in the courtyard of the house and will be in sight.

If you need to restrict outsiders access to the contents of the model, be sure to look for a design with a high reliability locking mechanism. This will allow you to provide yourself access to equipment inside the model at any time, but prevent outsiders from intruding into its work.
