A protective textile sleeve and method of construction thereof is provided. The sleeve includes a circumferentially continuous wall extending lengthwise along a longitudinal axis between opposite ends. The wall has a first section formed from a non-heat-shrinkable, non-elastic yarn and a second section formed from one of a heat-shrinkable or elastic yarn. The first section extends lengthwise between the opposite ends and spans (X) degrees about the circumference of the wall between opposite lengthwise extending edges while in an unshrunken or stretch. The second section extends lengthwise between the opposite ends and spans (360-X) degrees about the circumference of the wall. The heat-shrikable or elastic yarn of the second section extends continuously as an uninterupted yarn between the opposite edges of the first section.

A conduit system for protection of wiring or tubing comprising a tubular shaped conduit with latch system designed to allow insertion of electrical wiring without disconnection of the wiring or without threading the wiring through the conduit. The latch system is comprised of an internal latch, external latch or both and is formed to such that the conduit maintains its structural integrity while facilitating full and easy access to the electrical wiring contained within.

A communications cable (11) is provided with a pliant sleeve (12, 21, 31) to allow it to be more easily inserted into a conduit. One form of the sleeve (12) has hook (14) and loop (15) connected to each other so that the sleeve (12) can engage the cable (11). Another form of the sleeve (21) is spring-loaded to engage the cable (11). In a third form of the sleeve (31) has an adhesive (33) which attaches the sleeve (31) to the cable (11).

A method of fabricating a multi-compartment innerduct includes the steps of positioning a plurality of longitudinally extending, laterally spaced, strips of adhesive on a longitudinally extending sheet of fabric material, connecting adjacent of the strips together to form compartments, and attaching the compartments together.

A dadding tube (1) for enveloping an underwater conduit (2), such as a pipeline or a cable line, has at least one clamping portion (6), which comprises at least one deformation portion (6A, 6B, 6C) being integrally manufactured with the cladding tube (1), which deformation portion (6A, 6B, 6C) is a first wall portion of the cladding tube (1), which has a larger thickness in the radial direction than at least one second wall portion (8) of the clamping portion concerned, in such manner that by said larger thickness the first wall portion is, and the at least one second wall portion (8) is not, pressed against the underwater conduit (2) by a tensioning strap (7) being tensioned all round. The deformation portion concerned is easy to produce, durable and reliable. Thanks to the at least one clamping portion the dadding tube can be designed in harder and lower-cost materials than the soft, flexible poly urethane, which is usually applied nowadays.

A pliant tube is positioned in a duct thereby defining two compartments in the duct, one within the tube and the other between the tube and the duct. A pulling device, such as a pull tape or rope, is provided in each compartment and is adapted to be attached to a cable so that a cable can be pulled into each compartment of the duct.

Space in a conduit having at least one cable therein which is surrounded by a duct is recovered by longitudinally cutting the duct and removing the duct from around the cable. The duct may be pulled out of the conduit and past a blade to affect the cutting, or a blade may be pulled through the conduit to cut the duct while still in the conduit.

A communications cable (11) is provided with a pliant sleeve (12, 21, 31) to allow it to be more easily inserted into a conduit. One form of the sleeve (12) has hook (14) and loop (15) connected to each other so that the sleeve (12) can engage the cable (11). Another form of the sleeve (21) is spring-loaded to engage the cable (11). In a third form of the sleeve (31) has an adhesive (33) which attaches the sleeve (31) to the cable (11).

The invention relates to a modular and compact arrangement (200) of three phases (A, B, C) of a gas-insulated apparatus (100), that is suitable for placement inside a tunnel or a pipe (106) or another confined space. According to the invention, the three phases (A, B, C) are arranged in a triangle or side-by-side on a fixation part (103, 104) which includes a roller system (105; 105a, 105b, 105c, 105d). This allows the insertion of such a three-phase assembly (100) into confined spaces such as pipes or tunnels (106), without the need for access by workers or machinery. Furthermore, the present disclosure relates to a method for assembling and installing such a three-phase arrangement (100) into the confined space (106).
