When installing electrical units, care has to be taken at
every step of the way to ensure there is no loose wiring or connection.
It only takes one mistake to cause serious bodily harm and
even lethal damage to anyone who comes in contact with such a loose cord.
Likewise, there is a need for making joints, links, and such in the electrical
installation.
When it comes to large scale operations, the sensitivity of
materials to be used for these linkages are to be highly considered. Thus,
there came the need for many a composite
insulator in the electrical installations industry too.
The Journey of Insulators
The basic knowledge of insulators puts forward that they
should be materials which are very poor conductors of electricity. This way,
they can achieve their essential task without having to worry about the stress
and shocks from the electrical load which will be placed on them.
Furthermore, they should be safe enough that they do not
store electrical charges which could be harmful to operators or any other
individual near the insulation system.
Thus, the use of ceramics was borne.
Although ceramics did get the job done, there were a lot of
fundamental errors in their composition and physical properties which would
soon make them less than ideal.
For one, ceramics tend to be heavy. This created a problem
of its own during the transportation of these insulators from one place to the
other.
Speaking of transportation, the brittle nature of ceramics
wasn’t helping matters either. Extra care needs to be taken during movement to
ensure that they do not fall, crack, or break. Since they are naturally
brittle, they were also at a high risk of crashing when they have been in use for
long. This means extra costs of replacing cracked units in transit and extra
allocations to replacing the damaged ceramic insulators to maintain the
structural integrity of electrical systems.
All these, and more, were problems solved with the introduction
of silicone rubber insulators. Silicone has come to become the choice for
substation insulator systems for:
- Having
excellent electrical performance. The carbon atom number of silicon rubber insulator is
less than that of organic polymer, which effectively improves the reliability
of operation.
- Having excellent waterproof
performance. The surface of the silicon rubber insulator is the methyl group,
so it has hydrophobicity. Its pollution withstands voltage is 2-2.5 times of
that of ceramics. And it can be applied in the heavily polluted place without
cleaning.
- Being good at heat and cold
resistance. Because of its high bond energy and chemical stability, silicone
rubber insulator has better heat resistance than organic polymer. Moreover, due
to the weak interaction between molecules, the cold resistance is good.
- Being lightweight – even so that
it is about 80% lighter than glass, which is also lighter than ceramic
- Having amazing mechanical
strength to absorb shocks and prevent breakages during transport
- Reduction in the cost of
transportation and installation
- Being easier and cheaper to
maintain, among other things.
Getting
the right Silicone Rubber Molding Machine
When Choosing a silicon rubber molding machine, Dekuma may
be a consideration.
Dekuma assures electrical engineers of the best range of
silicone rubber insulators with the use of its novel Rubber Injection Molding Machine. Leveraging
knowledge from German and Chinese engineers who have worked jointly on the
project, they boast a solid track record of insulating materials that work the
way they are supposed to.
They have a series of molding machines that produce all
kinds of silicon rubber insulator used in the electrical industry. And under
the guidance of German technical consultants, the operation is very simple.
Having the largest hollow sleeve insulator production
equipment in all of China in their inventory, it is little wonder why Dekuma is
the choice of savvy and experienced electrical engineers and constructors.
