Key Factors
1. To maintain excellent electrical, mechanical characteristics upon cable operation.
The function of the semiconducting layer in the extra high voltage cable.

2. To block local deterioration of cables and make life characteristics better.
3. To minimize corona (partial discharge) phenomenon.

The merits LST-380CW
– The conductivity of the LST-380CW is excellent, would be more 1,000 times than the other products.

– If you consider to use LST-380CW in your LEAD or ALUMINIUM sheath cable, your EHV cable would have excellent electrical contact in its semi conductive layer.

– Then, the cable would not have electrical damage such a pro-demonstration and you should keep your EHV cables quality to be stable, long-life insurance and much more invisible merits than the others

Prompt release the energy by the strikes

the cable might have critical damage in the semi conductive layer because partial discharging and heating will occurs.

the cable might have critical damage in the semi conductive layer

4. To provide strong durability against compression and shrinking.
5. To make cable reliability and operation characteristics better.

The function of the semi-conductive layer

This loss is up to dielectric power factor

 

Ro : Outer semi conductive layer resistance Ω/m

Ri : Inner semi conductive layer resistance Ω/m

C : Capacitance of the insulation μ F/m W : 2πf
