In order to create an optimal working fencing system all components have to be of good quality. The electric fencers of Koltec are so powerful that they are able to face up bad insulators and bad conductors. This however is at the expense of an unnecessary high consumption of energy and with that the effectiveness of the electric fence system. KOLTEC advises to use conductors (wire, tape, cord) with a low conducting resistance, but above all insulators of a good quality.

Ring insulators
The much used ring insulators are indeed cheap and easy to mount, yet the working as insulator is moderate. The high charges, which are presently usual with electric fencers, lead to extensive loss of power caused by jump over/break down. During fog and rain the power easily flows to the post via the water film on the insulator. In extreme cases we even can see jump overs on the insulator. These spark jump overs are bad for the electric fencer. At long-term spark jump over the electric fencer can break down. In addition spark jump over cause’s inadmissible interruption on the radio/television and telecommunication.

Screw cap – and slit insulators
KOLTEC advises to use screw cap- and slit insulators as much as possible. These insulators are taking care of an excellent wire support with a minimal wear of the wire/cord. The shape of this insulator prevents spark jump over.

Screw cap insulator characteristics:
- Skirt shaped, for good water drainage.
- Because of its sophisticated shape there never arises a closed water film between wire and clamp, through which spark jump over can take place.
- Dirt repulsive, through which the insulator is being cleaned by rain.
- Large distance between wire and insolation clamp.
- With the screw cap the wire can be fastened and tightened
- The black synthetic plastic used is radiation resistant
- Long lasting
