SIVACON 8PS - LR system

The reliable busbar for a high level of protection in harsh environments from 400 A up to 6300 A, such as outdoor applications, tunnels and building networking.

Brochure

Busbar instead of cables The LR busbar trunking system ensures reliable power transmission under adverse ambient conditions. Thanks to the system's epoxy cast-resin housing designed with a high, IP68-rating degree of protection and high short-circuit rating, it is perfectly suited for outdoor applications – such as for power transmission in petrochemical industry installations, outdoor networking of buildings sections, and for supplying power to subway rail line tunnels.

Robust inside and out, versatile, and reliable

Forget about humidity and corrosive or salty atmospheres: These and similar environmental factors cannot harm the robust LR system. The epoxy cast-resin housing makes the system highly resistant to weather conditions and chemical substances, while also ensuring outstanding mechanical stability. The system's fire resistance rating of 180 minutes in accordance with IEC 60331 enhances the level of safety even further.

Optimum consistency for high currents

One convincing feature of the LR system is its versatility. Serving applications ranging from 400 A to 6,300 A, the system can be installed in flat, upright, vertical or horizontal configurations as needed. It can be optimally adapted to the given structural conditions using angles, connectors, and T-pieces, requiring little space for installation. And with its bolt-type terminal block, fitting and installation are simple and quick. The LR system is consistently integrated end-to-end, and, via adaptors, can be easily connected to LI and LD systems for indoor applications.

Applications The LR system is well-suited for use in harsh environments. Irrespective of whether the system is installed in the petrochemical industry, a subway tunnel, or for outdoor networking of building sections: The LR system ensures reliable power transmission – anywhere.

SIVACON 8PS: power supply for the age of digitalization

SIVACON 8PS busbar trunking systems – power for any application

The LR system is part of the comprehensive SIVACON 8PS product family. Busbar trunking systems are the innovative alternative to cables for a wide range of applications and sectors – whether for outdoor installations or the chemical industry.

Chemical industry

Power supply systems serving chemical facilities are subject to certain specific safety standards. With design verified components and connection units and a high degree of protection, the LR and LI busbar trunking systems ensure safe, reliable, compact, and economical power transmission and distribution at all times.

Power supply for tunnels and subway lines

Smoke extraction fans and power consumers in the railway track area of subway rail operations demand safe, secure and reliable power transmission solutions. Key factors in such applications are a high level of personal protection and prevention of vandalism. The LR system is well suited for application in tunnels.

Ships

Ensuring power supply to complex switchboards aboard ships poses a particular challenge. The salty, highly humid air, the high mechanical loads caused by the swell at sea, and vibration of the ship's engines make for harsh operating conditions, special ship bulkheads are required. The LR, LD, BD2 and BD01 systems have been certified for use aboard ships. In addition, thanks to their lower weight, they offer additional advantages compared to cable installation.
