Running an industry is not an easy task. You have many systems and many factors to keep in mind so that all the processes and operation in the industry are carried out in a proper way. One major aspect of any industry is the electrical network of that industry. The electrical networks are responsible for proper running of all the heavy appliances and machinery in an industry. For this reason, it is important to take care of the electrical networks and its components.
In every high voltage electrical network, there are many heavy and long cable installed which supply high voltage electricity. If these cables are not provided proper protection, they might get damaged severely as hamper the smooth supply of electricity to the industry. Compaq is a major cable accessories manufacturer in India offering a wide range of cold shrink and heat shrinkable power cable accessories that suits the needs of the clients. Some of the cable accessories offered by Compaq are discussed below.
Heat Shrinkable Semi-conductive Tubes
The heat shrinkable semi conductive tubes offered by Compaq are widely used in industries for bundling of a large number of high voltage cables. The bundling helps in keeping the cables intact and safe from environment and other external factors. The bundling of cables also makes it easy to identify the cable for maintenance and testing purposes. They are made from a high quality polymer called polyolefin, which has unique cross linking quality, which gives the product enhanced strength and extended service life. Some of the technical standards and specifications of Heat shrinkable semi-conductive Tubes are as follows.
| Properties | Value | Standard |
| Physical | ||
| Tensile Strength | 12 N/mm2 | ASTM D638 |
| Ultimate Elongation | 300% | ASTM D638 |

Heat Shrinkable Wraparound Jacket Repair Sleeve
These repair sleeves are manufactured from polyolefin, which is thermally stabilised and is provided with a liner on the inner side of the sleeve with a hot melt adhesive. When applied heat, the sleeve shrinks to its original shape and the adhesive liner melts to give a very tight seal, which protects the cables from moisture and other environmental factors.
Some of the technical specifications of Compaq Heat Shrinkable Wraparound Jacket Repair Sleeve are as follows.
| Properties | Value | Standard |
| Physical | ||
| Tensile Strength | 17 N/mm2 | ASTM D638/ISO37 |
| Ultimate Elongation | 300% | ASTM D638/ISO37 |
| Longitudinal Change | -10% (Max. | ASTM D2671 |
| Water Absorption | 0.2% (max.) | ASTM D570/ISO37 |
| Torchability | No split | TE 201 AOL |
