FIELD: electricity.
SUBSTANCE: proposed sealing lead-through insulating sleeve for information centres is made of a pair of U-shaped framework sections, each of which is formed together with thermoplastic elastomer seal having the shape of wave of corrugations; besides, corrugated edges of seals are open on open sides of U-shaped frameworks. The pair of such sections of the sealing lead-through insulating sleeve, which are connected to each other so that their corrugated edges are located in contact and in phase.
EFFECT: effective sealing for maintaining the air under pressure at simultaneous passage of different through elements, through a lead-through insulating sleeve, thus ensuring easy addition, removal or re-installation of through elements when compliance with dynamic changes occurring during operation of an information centre is required.
