In the recent years, the number of high power lasers devoted to particle acceleration has increased in Europe. Additionally to this, some synchrotrons and accelerators are integrating these lasers in its lines, increasing the scientific synergies. The HP laser must be transported in HV. The use of HV also permits good cleanliness in the optical set up. As addition, is necessary to create an adaptable and modular design where several chambers could be assembled together. One additional constrain is the stability. A new model of HV chambers is presented. These consist in a frame where the walls are exchangeable panels, which make easier the introduction of a new configuration of ports. The system was designed as construction blocks. For a proper connection of the chambers a new interior fixation and pushers system was designed. Thanks to this, coupling new HV chambers, the volume total can be also easily modified. Finally, a third generation decoupled system is integrated inside, consisting of a stable breadboard, this supported by six columns that implement a preloaded kinematical mount, providing both an outstanding stability and a fine regulation (1st RM: 77Hz).
