Cold tube generally refers to the cold shrinkage cable accessories, cold shrink cable accessories is to use the elastomer material (made) this product is a liquid silicone rubber, injection of vulcanization molding in the factory, then through hole enlargement, lined with plastic screw support form various parts of cable accessories, on-site installation, the pre expansion, set, in after processing, the end of the cable or tapping out internal support of plastic screw, pressure on the cable insulation, cable accessories, because it is in the room temperature by elastic retraction force, rather than the heat shrinkable cable accessories to use heat shrink, commonly known as the cold shrink cable accessories.
Cold shrinkage cable accessories has small volume, convenient operation, quickly, without tools, less scope width, and the product specifications, compared with the heat shrinkable cable accessories, do not need to use heat, and after installation to move or bend won't appear like heat shrinkable cable accessories accessories internal release risk between the layers.
It is important to note that during the period of storage, to ensure that the cold type parts have no obvious permanent deformation or elastic stress relaxation, or installed on the cable after can't guarantee enough elastic clamping force, thus can guarantee good interface characteristic.
Cold shrinkage cable accessories is use of elastomer materials commonly used silicone rubber and ethylene propylene rubber () injection of vulcanization molding in the factory, then through hole enlargement, lined with plastic screw support constitute parts of various kinds of cable accessories. On-site installation, the pre expansion woolly, in after processing, the end of the cable or tapping out internal support of plastic screw (support), pressure on the cable insulation and cable accessories. Because it is in the room temperature by elastic retraction force, rather than the heat shrinkable cable accessories to use heat shrink, commonly known as the cold shrink cable accessories. Early cold shrink cable terminal head just additional parts adopt silicon rubber insulation from the cold, electric field treatment still USES the stress cone type or stress belt around the package type.
Now generally adopt cold shrinkage stress control tube, from 10 kv to 35 kv voltage level. Cold shrink cable joint, 1 kv level using cold contraction insulation tube reinforced insulation, 10 kv level with joint semiconduction shielding layer inside and outside the cold contraction insulation parts. With cold contraction are three core cable terminal bifurcation branches.
Cold shrinkage cable accessories has small volume, convenient operation, quickly, without special tools and less scope width, and product specifications. Compared with the heat shrinkable cable accessories, don't need a fire heating, and after installation to move or bend won't appear like heat shrinkable cable accessories accessories internal interlayer release dangerous (for cold shrinkage cable accessories by elastic compression force). Compared with prefabricated cable accessories, although everything elastic clamping force to ensure that the internal interface features, but it's not like prefabricated cable accessories and cable is one to one correspondence, specifications.
It must be noted that, before installation on the cable, the prefabricated parts is no tension of cable accessories, cable accessories and cold contraction is under a state of high tension, so in the period of storage, must ensure that the cold contraction type should be no obvious permanent deformation of the parts or elastic stress relaxation, or installed on the cable after can't guarantee enough elastic clamping force, thus can guarantee good interface characteristic.
