Langmatz Polycarbonate Equipment Cabinets
For LV network switchgear, traffic control and general.
Langmatz reinforced polycarbonate equipment cabinets are made from an extremely robust, heat resistant, flame retardant, corrosion-resistant and weather resistant engineering thermoplastic: structural foamed polycarbonate.
Langmatz reinforced polycarbonate equipment cabinets are made from an extremely robust, heat resistant, flame retardant, corrosion-resistant and weather resistant engineering thermoplastic: structural foamed polycarbonate.
This material has excellent impact strength and is resistant to chemicals, oils and greases including cracking from solvents and aerosols.
It is completely safe to handle, cut, drill and tap. It is also fully recyclable.
Langmatz polycarbonate cabinets have proven their worth for well over 25 years and in installations throughout Europe, Australia and NZ. Polycarbonate is a long-lasting, weather-resistant material, unlike GRP (glass reinforced polyester) which is not generally suitable for New Zealand outdoor applications.
For LV network switchgear applications, where cabinets are often located in publicly accessible places, assurance of safety is provided by compliance with the requirements of AS/NZS 3439-5.
Safety and security are assured by the absence of exposed fixings, and the hinged lockable doors with fully insulated lock and 5-point latching. All mounting screws and fixings are 316 grade stainless steel. The lifetime of the doors is the same as the lifetime of the cabinet.
Mounting points are provided for fastening of vertical or horizontal DIN standard disconnects and fuse holders that withstand all normal forces applied during cable fastening and the installation / removal of fuses.
Ground planted and surface mount cabinets are available in a range of colours. Cabinets can be pre-fitted with busbars, mounting panels and equipment as required.
