RAPID FIT connectors for CELLFLEX® cables À`- Series

New upgraded connectors for CELLFLEX® cables Á` Series

The new connectors are backward compatible to the current cables but the current ones are not forward compatibleThis concerns the sizes: LCF 78-50, 114-50, 158-50

For the new cable LCF 214-50 the current connectors will be used furthermore

How to recognize the connector:The current (old) connectors Model No. ends with 060 (Plast 2000 sealing)or with 070 (O-Ring sealing) always (see connector body) e.g. 716M-LCF78-060

The new once of connectors Model No. ends with 062 (Plast 2000 sealing)or 072 (O-Ring sealing) always (see connector body) e.g. 716M-LCF78-062

Cable handling

Handle with care!

Do nothing which can deform the cablehandle with care during transportationnote correct stocking of cable and accessoriesdo not over tight the clampsdo not bend the cable to much

Make sure that the cable are clean alwaysDo not leave metallic particle, humidity dust or dirt inside the cableSeal the cable ends or connector heads

Note the installation instructions alwaysInstall all accessories e.g. connectors, grounding kits etc. inaccording to the installation instructions

Take care during transportation and installation, otherwise you will loose the good electrical

performance of the cable

Transportation of the drum

If a crane is used a special hanger is necessary to avoid damage of the drum flanges

If fork lifts are used, the forks must be long enough to engage both flanges of the drum to avoid cable damage!

The drum has to be secured carefully during transport!

Cable handling

How to handle cable rings

Lift up and turned the cable ring

Pull the cable step by step carefully – look always to the man which handles the ring in order to see how many cable is available

Protection by pipe rollers, wooden blanks etc.

Or: Roll out the cable ring along the ground of the cable line/route and lift the cable in the final position later

Wrong way!The cable ring has to be turned (like a drum) when pulling the cable, otherwise the cable will be twisted. If the twisted cable will be straightened afterwards the cable will be damaged in the twisted area

Cable handling

Cut the cable

For provisionally cutting we recommend to use a cable trim to cut the cable. It produces nearlyno copper chips during cutting.

Keep the cutting area down, in order to avoid dirt orcopper shavings falling into the cable !

Cable handling

Cut the cable

- cable will be deformed, but nearly no copper chips willbe produced during cutting. Deformed cables can be closed with hot shrink capswithout problems.

- a lot of dirt from the jacketand copper chips will be placed on the dielectric.Make sure that all particleswill be removed.

Before start the installation of the connector the cable has to be cut off again !

•Cut with cable trim:

•Cut with saw:

Cutting during hoisting/laying – Not for installation of the connectors

Sealing of cable ends

Seal the ends of the cable !We recommend to use heat shrink caps for sealing.

Shrink the sleeve with a soft yellow flame by evenly applying a constant flame with a circular motion, beginning at the closed end.

Rough up the cable jacket with emery cloth (280 grain).

Remove emery remnants with clean cloth and clean this area of shrinking with cable cleaner.

Installation of hoisting grip – open type

1. Place the hoisting around the cable, whereby the end with the connector shall be long enough to makethe connection to the antenna without opening the hoisting grip.Both ends with the two enclosed flexible wire strands are to beinserted in the two topmost net loops and then crosswise in the lower net loops and so up to the end (shoe close style)The meshes of the crossed wire strands shall not be smaller than the existing meshes of the hoisting grip

12. The two strand ends are to be knotted or clamped and to be secured in the net loops.The end of the hoisting grip can be fixed with tape.

2

3. Protect the cable area were the hoisting grip will be fixed to the ropefor example with the safety cloth, wool etc.

3

4. Clamp the hoisting grip with clamps to the hoisting grip or hang in a hook.

Cable laying

Horizontal runs

If the cable will be pulled on the ground, we recommend to use pipe rollers to avoid any damaged of cable jacket.

Even if it is necessary to drag the cable over sharp edges of buildings and tower members, protective measures must be taken (e.g. with wooden planks or observed by an installer).

Horizontal runs must be protected against the weight of accumulated ice and damage through falling ice or other objects.

Cable laying

Pulling in horizontal hollow tubes

The diameter of the hollow tube (or underground cable duct) shall be at least twice the CELLFLEX® cable diameter (e.g. min. 100mm for LCF 78-50).

The bending radii for tubes installation shall be at least twice the minimum bending radius (for multiple bending) of the respective LCF cable (see data sheet).

Inter- connections of several tubes must not damage the cable during pulling/pushing the cable. - Avoid any risk of blocking.

Avoid sharp edges during pulling the LCF cable.

Pulling of LCF cable can be supported by an additional layer of grease on the cable jacket.

If the cable will be pulled with a winch, we recommend to use a measuring device to make sure the max. tensile force (see data sheet) will not be exceeded.

Connector installationPreparation of cable

Before starting the installation:

•Cut the cable in this straightened& downward looking area min.0,2m from the end, remove all particles & dirt

•Tilt the end of cable downwards toprevent copper chips falling in tothe cable

•Straighten the cable end, approx. 1m

knocking from bottom side

Connector installationCorrect preparation & installation of connectors

Cut cable on the right place (top of corrugation) and in a right angle, therefore the use of our Trimming tool is strongly recommend.

After flaring (trimming tool recommend) remove all particles and dirt especially from the foam-dielectric. The cleaning of inner conductor is strongly recommend as well.

Make sure the connector fits in a straight line and tight him strongly (see installation instruction)

Well prepared cable, but connector is not fit in a straight line. By doing so you will lost the good electrical

performance (attenuation & impedance)

Connector installationPreparation under bad conditions

Insert the cable into building an mark the connector position

Pull the cable back to the outside and prepare the cable (preparation tools recommended)

Protect the prepared cable end (e.g. with caps or cloth) and push the cable into building by entering the wall gland very carefully

Install connector according to installation instruction

Not enough space for cable preparation – complete connector

installation from outside not possible because of to small wall

gland diameter

Connection installationProtection of connector head

If the connector will not be connect to antenna or equipment after the attachment of the connector soon, it is strongly recommended to protect the connector head, e.g. with plastic caps, to avoid any dirt or water

Protection of humidity & dirt Protection of

dust only

Connection installationMating of connector head

The connection has to be done with tools (not only by hand), to make sure that the connection is absolutely water tight.

The O-ring inside the connector will seal this connection absolutely.No additional sealing is necessary.

Min. & max. torques of mating: N = 6…8 Nm / 7-16 = 25…..30 Nm

Nearly nothing is well done!• Feeder cables not correctly fixed (must be

fixed on the end as well, Jumper cable has to fixed also)

• Jumper cable is bended to strong and to close to the connector (by doing so the cable will be damaged in a short time when moving due to wind)

• Cables laying in front of the antenna (that will influence the signal characteristic of the antenna).

• Grounding kits installed in a bended cable run (cable damaging and humidity)

• Grounding cables not in direct shortest direction to the ground (in case of lightning the voltage will damage some things)

• The grounding connection to the tower is corrosive because of the connection cooper to galvanized steel
