The installation methods have to be in accordance with the common standards. To ease insertion into tubes by means of compressed air or pulling wire, certified lubricants (e.g. paraffin) may be used. The use of soap or similar substances as lubricants is strictly prohibited. If a cable needs to be fastened, constrictions > mm must be prevented. The jelly filling inside the tubes can be removed using a tissue soaked in turpentine. It is advisable to cap the cable-ends during storage. Options Cables for outdoor use. Non-standard cable constructions, colors, details and/or additional information regarding specifications are available on request. 5
