Cable, metering boxes in thermosetting cubicles

Introduction

Cable boxes manufactured by ZPUE S.A. are based on the company's SKR fibreglass reinforced plastic enclosures and metal enclosures. They form the basic elements of cable-based LV power grids. Depending on intended requirements, they are used for the electricity distribution, electricity metering and to protect against the effects of overloads and short-circuits in low voltage cable grids. They allow feeding out from a low voltage cable route and supplying of consumers with an internal power line. They function as final or intermediate connections.

The offer of ZPUE S.A. includes a varied range of connection boxes: cabling, metering, cabling & metering, which were constructed in close cooperation with power distribution companies. Cabling, metering and cabling & metering connection boxes constructed with thermosetting plastic enclosures and metal enclosures may be installed outdoors in a free-standing version with foundations, as wallmounted or as part of a building façade.

Characteristics

modular design enabling the replacement of faulty parts,
a design which enables easy expansion of the existing connection box,
a design which enables both vertical and horizontal partitioning into power distribution company's section and recipient's section,
optimum depth of the cabinet enabling the installation of strip-mounted switch disconnectors,
the possibility of using access windows and access doors,
IP44 / IP54 protection rating in thermosetting plastic enclosures with the possibility of increasing to IP66 in metal enclosures,
excellent UV resistance,
possibility of manufacturing connection boxes with any layout and dimensions (does not require expenditures for the purchase of moulds),
environmentally friendly material,
effective labyrinth ventilation prevents condensation from forming,
high impact resistance obtained by definition of controlled breaking point,
plasticity of aluminium enclosures results in the enclosure deforming instead of cracking.

Compliance with standards

ZPUE S.A. certifies that the manufactured LV switchgears and connection boxes meet the requirements of the Directives of the European Parliament and of the Council: RoHS Directive No 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment and Low Voltage Directive (LVD) No 2014/35/EU on the harmonisation of the laws of the Member States relating to the making available on the market of electrical equipment designed for use within certain voltage limits and meet the requirements and standards in question.
