Heat Shrinkable Pole Cap

Heat Shrinkable Pole Cap

Product Details:


Product Description

Provided Pole Cap is manufactured from high quality cross-linked polyolefin material under the guidance of our expert professionals as per the set quality norms. It is fitted to drilling machinery and equipment. Further, offered caps are available in numerous sizes or known for their unique features like superior grade finish, sturdy design, corrosion resistance and greater durability. Offered Pole Cap mainly used in warping, splitting, cracking mainly from to surface, which can cause gaps and loosening of tool handles.

Pole Cap is Heat Shrink Cap, used to cover the top of the Wooden Power Pole & to protect it from ingress of water / moisture, thereby increasing Pole life. The caps are manufactured from high quality Cross-linked Polyolefin material.

The Best & Cost-effective Solution for long term maintenance of Poles :
  • Wood shrinks when losing moisture from the cell walls & swells when gaining moisture in the cell walls. This shrinking & swelling can result in warping, splitting, cracking mainly from top surface; which can cause gaps & loosening of Tool Handles. Wooden Poles with Pole Cap eliminates such problems & avoids extra cost of Clamps, used to tighten the gaps; thereby avoiding long term maintenance of wooden poles.
  • Use of Polecap typically adds some nominal percentage to the total cost of New Pole replacement. Precaution is always better than cure.
  • Hot melt adhesive lining provides 100% environmental sealing against weathering, moisture, contamination and adverse environmental conditions according to IP 68.
  • Resistance to UV rays & Ozone.
  • Versatile and cost effective, as 5 sizes of Pole Cap covers Pole dia. from 140 mm to 460 mm.
  • Service life of Pole Cap is more than 30 years.
  • Easy installation on concrete, wood, steel or composite poles in minutes.
Support Isulator, Polymeric Insulators
Benefits :
  • Once the heat applied, adhesive filled inside the top surface (optional) melts & penetrates into the pole cracks and cavities, thereby reinforces the top of the pole.
  • Provides excellent Impact resistance, i.e. when a Pole end covered with Pole cap hits on a sharp edge, it would not crack.
  • Prevents birds from perching (woodpecker damage) or nesting on top of round tubular & solid poles. Protects the top of the pole from damage caused by freeze and thaw conditions.
  • Eliminates outages from flash-over & electrocutions.
  • No maintenance after installation.

Polecap supplied by us are in an expanded form. When heated above 1250c they attempt to shrink back to their original dimensions, conforming to the objects they cover. Use a propane (preferred) or butane gas torch. Adjust the torch to obtain a soft blue flame with a yellow tip. Pencil-like blue flames should be avoided. Keep the flame moving continuously to avoid scorching the material.

    Pole Preparation :

    If necessary, cut the Pole end so that it is straight and even. Clean and de-grease the Pole surface that will come into contact with sealant. (Fig. 1)

    Installation of Polecap :

    Place the Polecap over the top of the Pole.(Fig. 2)

  • bustape1


    Shrink the Polecap into place, starting at the closed end and working towards the Pole Adhesive will be visible at ends. (Fig. 3)
