Is powder coating possible?
Powder coating is possible in all RAL shades. Surface coatings with powder varnish not only aid individualisation but can also be carried out for reasons of corrosion protection.
Besides the visual accents through colour and structure, the appropriate coating can, depending on the powder, also provide increased corrosion protection and the best insulating properties.
How much safety is guaranteed?
Mechanical safety
A clean transition is guaranteed at the joints – also at maximum load, and in the case of vibrations and knocks. The cable tray systems are subjected to load tests at our BET Test Centre. The basic principles for the tests of OBO cable support systems is DIN EN 61537 and DIN VDE 0639.
Electrical safety
Equipotential bonding is also permanently guaranteed without additional components. The cable trays are tested for EMC and impulse currents and are VDE-tested to DIN EN IEC 61537:2007.
Safety in the event of fire
With the RKSM, the maintenance of electrical functionality of the MPA is tested according to DIN 4102-12 and the cable trays can withstand loads of up to 20 kg/m at a width of 100–400 mm.
Which requirements does the cable tray fulfil?
Whether indoors or outdoors, in aggressive atmospheres or under special hygienic conditions: The cable tray systems can offer the perfect surface and materials for your cable support system, no matter what the requirements may be.
Cable trays, fittings and accessories are machined from high-quality sheet steel and are available with various surfaces. Different hardening or coating methods ensure tailor-made corrosion protection, specially tailored to the appropriate application:
