Types of cable Accessories
Aug 23, 2018

Many kinds of cable accessories, with different types of characteristics and limitations, generally can not replace each other.

The following are common:

(1) Wrapping: Made of rubber strip (self-adhesive) field around the production of cable accessories called winding Cable accessories, the attachment is easy to loose, less fire resistance, short life;

(2) Water type: With thermosetting resin as the main material in the field water, the selected materials have epoxy resin, polyurethane, acrylic acid, etc., the fatal disadvantage of such accessories is the cure is easy to produce bubbles;

(3) Molded type: Mainly used for cable intermediate connection, in the field to add mold heating, and cable melt into one, the accessory production process is complex and time is long, also not suitable for terminal joints;

(4) cold-shrink type: With silicone rubber, EPDM elastomer, such as the first expansion in the factory and add plastic support strip and molding.

In the on-site construction, pull out the supporting strip to make the pipe in the rubber inherent elastic effect of the tube contraction in the cable and made cable accessories most suitable for can not use open flame heating construction sites, such as mining, petrochemical and so on;

(5) Heat-shrinkable: The rubber-plastic alloy made with "shape memory effect of different components of the product, in situ heating shrinkage on the cable and made of accessories."

The accessory has the characteristics of light weight, simple construction, reliable operation and low price.

(6) Prefabricated: Use silicone rubber injection into different components, a vulcanization molding, only retaining contact interface, in situ construction when the cable is inserted into the attachment. The construction technology will reduce the unfavorable factors in the environment to the lowest degree, so the annex has great potential use value, is the development direction of XLPE cable accessories, but the manufacturing technology is difficult, involving a variety of disciplines and industries. Prefabricated accessories at the fork of the cable and the installation materials below the shielding are still used in the heat-shrinkable material, so it is in fact a combination of pre-and heat-shrinkable.
