Polaris PTLIH Ground Mounted Transformer Connectors
Heavy Duty Connectors with Bolted Lay-In Cable Clamps
- Lay-in cleats make connection of up to four cables per phase quick and convenient
- Compliant with ANSI C119.4 Class A for copper and aluminium conductors
- Conductor sizes from 35 to 500 mm²
Polaris PTLIH transformer connectors are application engineered for the New Zealand market to provide a secure, reliable and cost-effective meansof connection for ground mounted transformers.
Polaris PTLIH transformer connectors are manufactured from high-strength 6061-T6 aluminium alloy to provide premium electrical and mechanical performance. They are dual rated for copper and aluminium conductors.
No cable lugs are required, reducing tooling and installation costs and electrical losses.
The lay-in cable cleats make connection quick and convenient, especially with large cable cross sections.
By using torque-setting set screws, Polaris PTLIH connectors are re-enterable, enabling the connection of additional cables, or different cable cross-sections.
The range-taking design minimises inventory requirements; three sizes cover transformer ratings from 200 – 1500 kVA.
Polaris PTLIH connectors meet or exceed ANSI C119.4 Class A, which specifies connectors for use between aluminium-aluminium or aluminium-copper conductors used in electricity distribution networks.
