INNOVATION AND DESIGN FEATURESReliability and flexibility of operation

The modular construction principle of NKU provides the building flexibility of layout arrangement taking into account the technical requirements of the consumer.

• Convenient integration of the apparatus into the shell.

• Fast connection and cable laying.

• Interchangeability of the functional units.

• Embedded digital control and monitoring system of NKU.


The soleplate allows changing NKU height and also gives it additional rigidity.

If necessary, you can install up to two soleplates one upon the other.

The unique soleplate structure is equipped with detachable panels. The soleplate allows transporting the cabinets during installation works in confined spaces using a forklift.

Movement of cabinets with a forklift at the installation site reduces the preparation time of the product during commissioning/


The panels are equipped with a quick-release fastener, which provides quick access to embedded equipment in case of necessity.

Uninterruptible power supply

Fast access provision to the equipment and automatic circuit-breakers of outgoing lines when servicing.

The use of rotating panels, made in the same style with the plastrons of the cabinet.

The unique Linergy Evolution aluminum busbar system.

• Efficient heat dissipation.

• Initial short-circuit current up to 220 kA.

• Visual visibility of the contact area.

• Transition resistance reduction of the contact area.

• Wiring to the busbars without drilling holes.

Time reduction to perform routine maintenance of embedded equipment and automatic circuit-breakers.


Safety of personnel and equipment

Switchgear protection against the unauthorized access by means of the transparent door with a lock.

• The possibility of visual control of the state of switching devices and apparatus is maintained.

• Visual control of the state of the automatic circuit-breakers and light signaling equipment.

• Access limitation to the switchgear.

Rigid external shell of the design provides the degree of protection against the mechanical shock as per IEC 62262 up to IK10.

Attractive external view

Cost reduction for the system performance of the object’s power supply, the increased cycle of routine maintenance


Type tests reports and also compliance certificates are prepared by the laboratories certified in the accreditation national system “Rosaсcreditation”. However, the product meets the requirements of European standards ISO/IEC, which have stricter criteria.

The consumer receives a low-voltage complete device NKU-SESH-M, the quality of which meets both the Russian and European standards

BLOCK DIAGRAM OF DIGITAL CONTROL SYSTEM


DESCRIPTION OF THE WORKING AREA OF DISTRIBUTION CABINETSHeight of module MWorking space for arrangement of panels with apparatus on height is divided for clarity. The height of one module (1M) is 50 mm (1M = 50 mm).

Maximum quantity of modules in the distribution cabinet is 30 M.

Section for cable connections can be located both on the left and on the right side of the distribution cabinet.


PlastronFront panels or plastrons covering wiring boards with the apparatus installed on them have different configuration and are made in the same style and chosen due to their height in modules.

The plastrons are equipped with fast-release fastener and do not require special tools for demounting.

To provide easy access to the equipment and automatic circuit-breakers of the outgoing lines during maintenance the plastron can be installed on the hinges.

Time reduction to perform routine maintenance of embedded equipment and automatic circuit-breakers.

The quantity of the used modules for wiring boards with different automatic circuit-breakers can be clarified in TI-205-2017 at the company web-site http://electroshield.ru

TRANSPORTATIONREQUIREMENTS

NKU-SESH-M is supplied as transport groups consisting of one or several cabinets connected together.

The package can be of two types:

• wooden pallet with wrapping in inhibited heat shrinkable film;

• wooden container.

The equipment is supplied on the pallets or guide blocks. Final unpacking of the equipment shall be made, if possible, before installation.

When unloading NKU-SESH-M one shall transport lifting it from below or gripping it from above.

When lifting from below the equipment can be lifted from the front or back side with a stacking truck or a fork lift truck. It is required to follow safety rules, equipment shall be fixed with safety belts during transportation.

When using an overhead crane gripping the equipment from above, it is required to use the corresponding slings. They shall be enough strong and in good condition. The slings shall be fixed to four lifting rings on the equipment. It is required to adjust the length of the slings as per the size of the distribution device in such a way that the angle between the slings does not exceed 60°.

In cases when a transport group includes more than two cabinets connected with each other, it is required to use the cross-beam with direct mount to support elements of the distribution device.


SERVICE SOLUTIONSElectroshield Samara provides a warranty and post-warranty service of its own manufactured equipment, as well as modernization of the obsolete equipment of other manufacturers.
