Rated voltage 66kV, lightning impulse withstand voltage ≥ 250kV, power frequency withstand voltage ≥ 125kV (continuous for 30 minutes); Partial discharge capacity ≤ 5pC (compliant with IEC 60840 standard).
Main structure: double-layer silicone rubber cold shrink sleeve, built-in prefabricated stress cone to optimize electric field distribution; Copper braided shielding mesh layer achieves full circumference metal shielding recovery.
66/72.5kV cross-linked cable direct burial/tunnel laying scenarios, suitable for corrosion-resistant environments in chemical industrial parks;
New energy booster station collection line renovation to meet harsh working conditions such as salt spray and high humidity.
Prohibit the use of axial cutting cold shrink tubing to avoid stress concentration leading to tearing;
Avoid external bending within 24 hours after installation.
