Composite Line Post Insulator
1. The silicone rubber housing of Composite Line Post Insulators
were taken shape by whole injection. It has good hydrophobicity,
hydrophobicity migration and soil resistance, as well as excellent
electrical insulation properties and aging resistance, which could
prevent effectively those accidents of pollution flashover so as to
ensure the safe running of high voltage transmission lines.
2. Corrosive Resistance Fiberglass Core
Excellent resistance to high temperature, stress corrosive &
Better damping Performance
High tensile strength (＞1200Mpa)
Excellent creep resistance
Excellent anti-fatigue fracture properties
Diameter of the core rod: 70mm
3. End fittings are crimped onto fiberglass rod with voice-operated
displacement type crimper. The insulators with this crimping
technique have high mechanical strength and small dispersion.
Taking the most advanced automatic overall injection moulding
technic and connection method of crimping for production and
assembling, and the whole crimping procedure controlled by computer
and the crimping result monitored by ultrasonic detector to assure
each product is qualified.
Crimping Machine of Line Post Insulators
1) Gray Silicon Rubber for sheds/ housing.
2) Glass-fiber reinforced epoxy resin rod (ECR type) for core.
3) Hot Dip Galvanized Cast Iron/Steel for End-Fitting (Flange /

Manufacturing Flow Chart:
1.Before dispatched, the goods will be performed routine test and
sample test comply with related standards. In case damage during
the transportation, each one’s sheds and housing will be checked
thoroughly. Superficial defects of an area greater than 25 mm² (the
total defective area not to exceed 0.2% of the total insulator
surface) or of depth greater than 1mm.

4. Testing Equipment: Cantilever Load Test Machine
1. All composite insulators are packed in weatherproof containers
in order to protect the products during land, air, and sea
transportation. Several different grades of packaging can be
offered depending on the mode of transport and the expected storage
2. Each container is marked with the number of insulators it
contains, the catalog number, the manufacturer’s/Clients name, and
any other customer requests.

Cautions on installation, storage and transportation
1)Before installation, the goods should stored in dry warehouse. It
shouldn’t expose to oil and petrifaction products, and should take
actions to keep away from rats.
2)During transportation, Hardware fittings and other heavy objects
shouldn’t be stacked on the insulators directly to avoid damaging
the insulator’s sheath. So it should be unpacked only at the
3)Be careful and avoid edge tools cutting the insulator’s sheds
when unpacking the Box.
4)Don’t drag the insulators on the ground at installation site..
5)Be careful not to bend the insulator too much,which avoid the
excessive bending stress of insulator’s rod.
6)Insulators should be carried by two or more persons in manual
7)The rope should be attached to the end-fitting rather than hang
it directly on the insulator’s sheds when in hanging installation.
8)It need to pay attention that the ring-shaped smooth surface of
corona ring should be face the insulator’s shed when installing it.
9)Don’t treading and climbing on insulators..
10)Don’t treading on the mounted corona ring or hanging rope and
heavy objects on it, in case of cause the corona ring to loose or
damage the surface.
11)Try to avoid excessive bending or torsional stress to the core
rod during installation, don’t rotate the insulators that has been
fixed or loaded.
Please note goods type, specification, quantity and delivery date
when quote it.
Except varied standard composite insulators, we design and supply
goods complied with customer requirements.
