What problem does this cause?
The installed inverters for the PV systems require the laying of AC supply cables, which are often 185 mm². These have a diameter of 25 mm or even larger. This makes the cables more rigid and they can only be routed through our seals with a large bending radius. Our roof ducts, such as the gooseneck, reach their limits due to the curvature.
How did we solve this?
The solution is an adhesive and/or fixed/loose flange construction, which is welded on with straight pipe sleeves at a 45° angle. This allows the cables to be fed through easily without being severely bent. The fixed/loose flange construction is manufactured in accordance with DIN 18533. Pipe diameter, base plate and the intermediate length between base plate and fixed/loose flange are manufactured to customer specifications. The conduit sleeves through which the cables are routed are sealed watertight and gas-tight with a suitable rubber press seal (GPD).
