25kV 133% Insulation Level – Medium Voltage Cable for Critical Infrastructure

This 25kV 133% insulation level medium voltage cable is engineered for reliable power transmission in demanding industrial and utility environments. Featuring a pure copper conductor, EPR insulation, copper tape shield, and durable PVC jacket, it delivers exceptional electrical performance with 320 mils insulation thickness. UL1072 certified and Type MV-105 rated for 105°C continuous operation, this cable provides enhanced dielectric strength against voltage surges and system disturbances. Suitable for installation in industrial plants, power substations, power generation facilities, and mining operations, the copper tape shield ensures effective grounding while the PVC jacket resists moisture, oil, and chemicals commonly found in harsh industrial settings. The 133% insulation level offers superior safety margin compared to standard 100% construction, making it the preferred choice for critical medium voltage distribution systems where operational reliability is paramount.

FAQ

What does 133% insulation level mean for 25kV cable?

It provides extra dielectric strength and safety margin against voltage surges and switching transients beyond standard 100% insulation.

Why copper tape shield instead of other shielding?

Copper tape offers excellent fault current capacity, low-impedance grounding, and superior EMI shielding for sensitive protection equipment.

What is the maximum operating temperature?

MV-105 rating allows continuous 105°C conductor operation, with short-circuit withstand up to 250°C for limited durations.

Can this cable be installed outdoors or direct burial?

Yes, the PVC jacket resists moisture, sunlight, and chemicals, though proper burial depth and mechanical protection are required per code.
