At the laying of the corrugated pipes it is necessary to avoid acute angles, and also near location of a few corners. - Working distance for broaching of a wire in the pipe composes 20-25 m with a maximal amount correctly laid out 4-5 corners. – If it is necessary to increase of whole run of pipe and number of corners, you must set transit boxes on corners or on places, near to the middle of the whole run of pipe. - Broaching in one pipe simultaneously a few networks is not allowed. - Laying of every type of communications is made in separate, intended only for this purpose, pipes and boxes in the distance one from another.

• At monolithic building the corrugated pipes of heavy series are laid previously to concrete placing and fixed to supporting metal structures, broaching of wires is made after forming of wall
• Internal communications on the basis of corrugated pipes allow to use the interchangeable wiring during all the term of exploitation of building.
• To the lighting devices is tricked into a pipe by a diameter 16 mm.
• For the laying of telephone and signaling networks uses a pipe by diameter of 16 mm.
• To the switches and wall outlets is tricked a pipe by a diameter no less than 20 mm.
• For the laying of coaxial network is recommended the use of pipe with diameter no less than 25 mm.
• Connection of basic distribution box with analogical in other room and with central distribution box by means of pipe with diameter 25 mm with the laying of rubber pipe.
• For connection of electric boxes between one another it is recommended to use a pipe with diameter no less than 32 mm with the laying of rubber pipe.
• For connecting between floors a pipe is used with a diameter 40, 50 or 63 mm.
