Oversheath Integration of Optical Fibres and VALCAP Grid Monitoring Integration o of O O

you get information of expected future loads, for every day and every hour. So you can pro-actively manage the energy load trans-mission of your grid. For more information please request the brochure “VALCAP Grid Monitoring”. An extruded polyethylene sheath is provid- ed as the standard solution. With respect to its excellent mechanical strength it is the optimum for buried cables. If required, a conductive layer can be provided on the outside. For special applications different sheathing material may be used, optimized for the purpose. For distributed temperature gauging optical fibres can be integrated for both, three core and single core cables. Today ampacity of your grid is restricted by thermal limits based on fixed and standard- ized parameters with high safety margins. It is not possible to control grids dynamically and in real time.With

Cabling and Armouring

For the conventional pipe type cables as well as for the CityCable, laying-up of the three cores and provision of the strong steel armour is an essential feature. Therefore, VALCAP you can maximize the effi- ciency of your existing grid: continuous temperature monitoring and evaluation of the actual environment conditions along power cables and overhead lines allow you to de- cide precisely how much load your grid can transport safely.And nkt cables disposes also of the appropriate machinery to carry out these production steps. VALCAP will even do more for you: With its intelligent software companion ADAPPRO

Single Core XLPE Cables with Copper Wire Screen and APL Sheath

These cables can be supplied in the standard design, i.e. with insulation thickness as already used for several decades. Due to improvements in material and manu-facture it was possible not only to develop XLPE cables for extra-high voltage, but also to reduce the insulation thickness of the established high voltage cables. The effects are smaller dimensions and weights, both enabling longer supply lengths on standard drums, resulting in a smaller number of joints which in turn means less installation work and less disturbance due to open joint bays. Overall, a significant cost saving is achieved with the XLPE cables of advanced design. Based on experience gained from tests and long-term service, further tables present data of cables with optimized design.
