Accessories and Features
glass insulators
Locking Devices
The plant manufactures insulators with W-clips and split-pins, which corresponds to the Russian and international standards.
Split-pin provides more reliable coupling in a string, as the cross-section area of the split-pin is 2 times more than the crosssection area of the W-clip. The insertion of split-pins and bending of the legs are made at the plant.
It is necessary to note, that with such a universal coupling it is possible to make a string of insulator units with different types
of locking devices.
Insulator with W-clip
Insulator with split-pin
Zinc Sleeves
The characteristics of insulators with a zinc sleeve fully correspond to those of
insulators without it. The zinc sleeve, being "a sacrificial electrode", prevents for
a long time from corrosion of a pin caused by d.c. and environmental conditions
(a tropical climate).
1. Cap.
2. Locking device (split-pin).
3. Glass part.
4. Gasket.
5. Pin.
6. Binding material.
7. Zinc sleeve.
When the insulators are stored in a dry atmosphere, especially at high temperature,
the cement bond loses its moisture. It resulted in a slight shrinkage, in this case
increases the clearance between the glass and cement bond. In some cases the
increased clearance can lead to a rotation of the pin relative to the glass by a
few degrees. This rotation arises from the manual effort with characteristic clicking
noise. This phenomenon disappears once you move the insulator into the atmosphere
with normal conditions or being under load when assembling on the line. This
phenomenon does not affect an insulator performance.

packing
Packing
Packet with Crates
Each packet with crates includes several
wooden crates placed on the pallet.
For packing manufacture the "screwringed" nails are used. They have ring
grooves on the stem that create the additional friction force and the nails keep
the nailed timber more fixedly.
The pallet packer wraps round the packet
with insulators by strechtape in a few
layers to strengthen it for transport to
the consumer.

Wooden Crate
The pallet packer wraps round the packet
with insulators by strechtape in a few
layers to strengthen it for transport to
the consumer.
Package with Boxes (PB)
Slatted Crate
Wooden Cylindrical Crate
The advantages of this type of slatted
crate:
Convenience of disassambly (box does
not require special tools to open it: only
untwist the wire and box is opened).
During transportation empty boxes laid
out in crate and to take up a little space
in the truck.
The packing of insulators supplied by GIG is made of wood treated in accordance with the international standard ISPM-15.
When the insulators are stored at the open storage ground, the wood may darken under ultraviolet exploration or dust.
The impact of these factors on the packaging material does not reduce its mechanical strength.
