Electrical Contact
Duties of electrical contacts include:
•To establish a reliable electrical connection
•To achieve the best possible mechanical and thermal strength
under different operating conditions
•To maintain a high degree of stability against external influences
•It requires many years of experience and an in-depth know-how
to meet the above provisions.

Schunk
Motorscrope is an advanced fully portable measurement system, and ideal
for collecting data of Eccentricity of commutator and slip ring. For
example roundness and high bar data.
Features:
•Simple installation
•Receiver suitable for all current holder systems
•Easy evaluation of data and documentation via Windows
•Testing at motor potential
•Inter-grated printer for immediate analysis
Commutator
Maintenance Products
•Commstones With comstones, it is not necessary to take a
machine out of service to surface its commutator and slip ring. It can
quickly remove flat spots, high bars,grooves, ridges and high mica. Five
grades (roughness) and some standard sizes for choice.
•Rubber Bond Cleaning Stones
Rubber bond cleaning stones are excellent for removing surface imperfections
from any metal, recommended in commutator maintenance for periodic cleanings
of surface.
•Brush Seater With brush seater, carbon brushes of any material can be easily and accurately seated for a good contact with commutator and slip ring.
•Garnet
Commutator Paper
Commutator Paper is non-condutive and is used for pre-shaping new copper
and carbon brushes and for cleaning and burnishing comutator surfaces.
3 grits, 7 widths and 25 yards rolls for choice.

•Commutator
Grinding Tools
The commutator Grinder assures concentricity of the commutator or slip-ring
by precision grinding while it is turning in its own bearing at operating
speeds and temperature, with centrifugal force holding each bar in place.
It is not necessary to take a machine out of service to resurface its
commutator or slip-ring.
| •Activated carbon is an adsorbent, available as black granules, spheres, pellets or powder which is used in the purification of air, gas, vapor and liquid in food, mining, automotive, chemicals, environmental, precious metals recovery industries, together with numerous other applications. It is mainly manufactured from carbonaceous vegetable or mineral raw materials by chemical or high temperature steam activation. All activated carbons are characterized by an extensive network or internal pores of neat molecular dimensions and consequently, internal surface areas of 500 ~ 1500m2/gm or more. The pore size distribution and chemical/polar nature of the surface markedly influences the selective adsorption function. Typically, 1m3 of activated carbon with 0.3m3 of internal pores can adsorb 30m3 or more of a gas, even if present in low concentrations in a carrier. |

•We
are the agent of activated carbon product of Haycarb Limited, which located
in Sri Lankan, with a 112-year history and expertise in manufacture, domestic
and internal trade, is one of largest and most diversified private sector
organizations in the country. Its numerous divisions, subsidiary and associate
companies employ over 4000 (principally in various export based industries).
As a largest exporter of charcoal and 70-year tradition of pioneering
coconut by-product utilizing industries, the conversion of charcoal to
finished activated carbon, prior to export, was viewed as natural forward
integration of Hayley's activities. Haycarb also strength lies in low
operation cost (to maintain competitive price for our clients), hi-tech
processing, good quality control and professional management to meet the
market trend.
