## Abstract

An UTP cable of improved alien crosstalk characteristic according to present invention comprises, at least two pairs that is formed to have pitch by twisting at least two wires coated by insulation material; a separator including partition wall separating the pairs from one another; a sheath wrapping the pairs and the separator; and a spacer separating the pairs from the sheath, wherein the partition wall of the separator is formed to make an acute angle θ with the spacer.

## Claims

### Claim 1

An Unshielded Twisted Pair (UTP) cable of improved alien crosstalk characteristic, comprising:
at least two pairs, wherein each pair is formed by individually twisting two respective wires coated by an insulation material;
a separator including a partition wall and a supplemental partition wall which separate the pairs from one another, wherein the supplemental partition wall protrudes from a center portion of the partition wall, wherein a first side of the supplemental partition wall forms a first acute angle with the partition wall and a second side of the supplemental partition wall opposite to the first side forms a first obtuse angle with the partition wall;
a sheath wrapping the pairs and the separator; and
a spacer separating the pairs from the sheath, wherein the spacer includes a support portion facing the pairs and having a first portion and a second portion positioned opposite to the first portion over the partition wall,
wherein the partition wall of the separator forms a second acute angle with the first portion of the support portion of the spacer and forms a second obtuse angle with the second portion of the support portion of the spacer.

### Claim 2 (depends on 1)

The UTP cable of improved alien crosstalk characteristic according to claim 1, wherein,
the spacer further includes ribs protruded from the support portion and separating the support portion from the sheath.

### Claim 3 (depends on 1)

The UTP cable of improved alien crosstalk characteristic according to claim 1, wherein,
the support portion includes first and second supports connected with both end portions of the partition wall, and
plural ribs are connected to the first and second supports respectively.

### Claim 4 (depends on 3)

The UTP cable of improved alien crosstalk characteristic according to claim 3, wherein,
said plural ribs have different height or thickness from each other and said plural ribs are formed at respective first and second supports connected with both end portions of the partition wall.
