Tech Tip – Why Is Ancor Wire More Flexible?

Wire flexibility depends on two important factors:

1. Type III Fine Copper Stranding

The finer the individual copper strands, the more flexible the wire becomes.

Ancor uses Type III ultra-flexible tinned copper stranding, consisting of numerous 30 AWG (0.010") strands that exceed minimum marine standards.

For example:

• 16 AWG Ancor wire contains 26 individual strands

• 4/0 AWG Ancor wire contains 2,109 individual strands

This allows easier installation through rigging tubes, conduits, and confined spaces while reducing stress on electrical connections.

2. Premium Flexible Insulation

Ancor's premium vinyl insulation has a lower durometer (hardness) than many competing products.

Benefits include:

• Easier cable routing

• Better vibration resistance

• Reduced risk of insulation cracking

• Longer service life

• Improved installation in tight spaces
