20kV Cold Shrink Cable Joint \/ 20kV Cold Shrinkable Power Cable Terminal<\/b><\/strong><\/h2>\n

Cold shrink cable joint is made of liquid silicone rubber and EPDM rubber with hydrophobic performance. High elasticity and ability to shrink ensure powerful and constant active pressure between rubber and cable that can respond to expanding or shrinking cable diameters under load cycle.<\/p>\n

Power and technology<\/strong><\/h2>\n

Cold contraction cable accessories is the use of elastomeric material (commonly used with silicone rubber and EPDM rubber) in the injection molding equipment vulcanization injection molding, and then by expanding and lined with plastic spiral support composed of various cable accessories. When the installation is in place, the pre expansion parts are sheathed at the end or the joint of the processed cable, and draw out the inner supporting plastic spiral strip (support), which is pressed on the cable insulation. Because it is at room temperature by<\/p>\n

elastic recoil force, rather than like heat shrink cable accessories to be used to heat the contraction, it is commonly known as the cold shrink cable accessories. Early cold contraction cable terminal head just additional silicone rubber insulation used and contraction parts, electric field treatment still use should stress cone type or stress zone around the package.<\/p>\n

Now generally adopts cold contraction stress control tube, the voltage level from 10kV to 35kv. Cold contraction cable joint, 1 kV level uses the cold contraction insulation tube to strengthen the insulation, the 10kV level uses the inside and outside the semi conductive shield the joint cold contraction insulation piece. Three core cable terminal bifurcation with cold contraction set branch.<\/p>\n

The characteristics of cold shrinkable cable accessories<\/strong><\/h2>\n

Take the most advanced full of cold technology, without flare and special tools, installation, only the line core is drawn out, elastic body will rapidly shrink and close to the installation site.<\/p>\n

A silicone rubber has excellent insulation and high elasticity, after the installation of remains of cable body suitable radial pressure, the interfacial bond, not because of cable runs of respiration and breakdown. The stress control part and the main insulation composite are integrated, which effectively solves the problem of the electric stress concentration in the outer shielding surface of the cable, which ensures the reliability of the insulation and the safety of the operation. All products have been manufactured in the factory. Without special training, simple installation and operation, and don’t use the fire, time-saving and labor-saving, cold shrinkable automatic reset technology, easy installation without breaking a sweat, greatly reduced due to the quality accident caused by the improper operation, but also solves the phenomenon of prefabricated cable accessories contraction is not tight or don’t go in.<\/p>\n

Summary<\/strong><\/h2>\n

Terminal insulation material is made with high quality silicon rubber material and, it has good hydrophobic performance, when the droplets after the above, ready to roll down, do not form a conductive film of water and has a hydrophobic self-healing properties. In addition, it has a strong insulation, resistance, corrosion resistance and UV resistance, the biggest advantage is to ensure long-term use of stable performance. Long life, the same life with the cable body.<\/p>\n

Accessory cable terminal head, has a unique material formula and manufacturing process, which closely attached cable main insulation, the body of the cable provides a constant radial pressure, small amount of partial discharge, high starting voltage, impulse insulation level is higher than the level of existing standards, and the cable body with ‘breath\u2019.<\/p>\n

The national standard GB50168-92 ‘cable line construction and acceptance code section 6.1.3 provides: the manufacture of plastic insulated power cable terminals and connectors, should prevent dust, debris fall into the insulation. Is strictly prohibited in the fog or rain”. If we do not pay attention to the influence of environmental factors in the production, will cable head\u00a0insulation due to dust, impurities, such as the formation of air gap and under strong electric field occurred partial discharge (PD), and then to insulation breakdown, resulting in the breakdown of cable head fault. If made in a humid environment, cable is easy to be affected with damp and makes the overall reduction in the level of insulation. In addition, it is also easy to moisture from entering the gap formation and the emergence of partial discharge.<\/p>\n

Cold shrink installation analysis:<\/strong><\/h2>\n

1.All of the silicone rubber are high quality liquid silicone rubber, with excellent insulation and high elastic.<\/p>\n

2.With the cable \u201cbreathing\u201d effectively reduce the partial discharge and gap discharge;<\/p>\n

3.No magnetic constant spring, avoid the eddy current and suspended potential.<\/p>\n
