The maintenance shaft with longevity
Inspection chambers should protect your lines, cables and connections safely and reliably. Finding material that meets these requirements is a special task. The material must be resistant to grease and oil, must not break easily and must have a high resistance to water. In addition, the material must not become electrically charged and must withstand mechanical stress. All these conditions are best met by ABS plastic. Acrylonitrile-butadiene-styrene copolymer has high strength, is riser and tough. In addition, the plastic has high thermal shock resistance and is weakly hygroscopic. The long service life and excellent properties make ABS plastic the best material for your inspection chambers.
Good protection with IP54
To ensure that your cables and wires are well protected, and that we can certify this, the maintenance chambers must undergo various tests to prove their degree of protection. The tests are used to determine how resistant the inspection chambers are to the ingress of dust and water. The result is indicated by means of two code numbers, which stand behind the IP (International Protection). The first number indicates the resistance to dust and dirt penetration. Thus, with the IP54 protection rating, you know that the shafts have complete protection against contact, but dust can penetrate in small quantities. The second code number describes the resistance to water. With the high-quality maintenance shafts, you get a product that is protected against splash water from all sides, but must not be used permanently under water.
How do I use the manhole?
The main purpose of an inspection shaft is to bring cables and pipes together. Here it is important to consider the size of the cables. Inspection chambers are primarily used for power cables. First of all, determine the cross-section of your supply line and open the appropriate inlet point on the shaft. Now decide how many branches you still need and open these as well. Then you can connect the cables in the inspection chamber, divert them or connect them to measuring instruments. To better protect the connections and cables, some electricians use a layer of resin. Now it's time to put the cover on the manhole, and then close it tightly with 4 screws in the corners. Be sure to place inspection chambers on hardened surfaces.
Difference between junction box and inspection chamber
While a junction box can be found in the house, basement or garage, the inspection shafts are more likely to be found outside, in the ground. The inspection chambers are designed for the distribution and protection of heavy current, whereas normal junction boxes are designed for the distribution, respectively merging of cables and wires with common household voltages. Therefore, in contrast to inspection chambers, junction boxes also require significantly less space.
