Technical Introduction

Clamping Technologies Compression technology (Progress® Line) Lamellar technology (Syntec® Line) 1. O-ring 4. sealing insert / reducing sealing ring 2. lower gland part 5. compression nut 3. lamellar insert

Comparison clamping technology Compression technology • Excellent aging behaviours • Smooth pressure around cable, large pressing area • Ideal for application with movement between cable and gland vibration e. g. rolling stock and transportation systems • Heavy duty outdoor applications • Best possible sealing behaviour (e. g. underwater application)

Comparison clamping technology Lamellar technology • Large clamping range • AGRO lamellar: hexagonal compression avoids a torsion of the cable • AGRO lamellar: pre-fixing of compression nut facilitates over-the-head mounting • AGRO lamellar: large wrench flats for easy installation

Technical features of Syntec® cable glands

Materials of cable glands Synthetic • Polyamide PA 6 • Polyamide PA 6 GF 30 (glass-fibre reinforced Polyamide) • AGROMID Polyamide PA 6 GF 30 (glass-fibre reinforced, impactresistant, heat aging, special modified) Metal • Nickel –plated brass (Cu. Zn 39 Pb 3) • Stainless steel A 2 A (AISI 303) • Rustproof and acid-resistant stainless steel A 4 (AISI 316 L)

Materials of the Sealing Inserts • TPE (Thermoplastic elastomere) Temperature range: *-40°/+100°C • NBR (Acrylyonitrile-butadiene-rubber) Temperature range: *-40°/+100°C ideal for hole drilling for multiple cables • FPM (Fluorine-rubber) (Viton®) Temperature range: *-40°/+200°C • CR (Chloroprene-rubber) Temperature range: -30°/+100°C * TPE / NBR / FPM: -60°C if: no dynamic load; no relative movement between cable and cable gland; not suitable for Ex glands

Type of Entry Threads • Metric Threads M 6 to M 115 mm • Pg – Tank thread Pg 7 to Pg 48) • Gas Pipe Thread G 3/8” up to G 3” • NPT (National Pipe Thread) NPT 1/8” up to NPT 2” (American conical thread, no counter nut required)

Entry Thread Lengths • Short entry threads are mainly used when the cable gland is directly screwed into a female threaded counterpart • Long entry threads are mainly used when the cable gland is fixed with a lock-nut

Type of Sealing Inserts – Progress Line • Cable glands with short sealing inserts. • Cable glands with overall length insulated sealing inserts. • This type of sealing insert is electrically insulated on its full length.

Type of Sealing Inserts - Progress One-piece sealing insert • guarantees highest pull-out resistance Two-piece sealing insert • larger clamping range • Reduction of cable gland types on stock, increased flexibility

AGRO EMC Cable Glands

Metallic Pipes and Cables Metal pipes and cables act as antenna. Pipes and cables are the enemy of EMC. Electromagnetic fields use the surface of pipes and cable in order to spread. Parasitic current Data link Insulation or air Cable shield Enclosure

Shielded Cables In order to achieve the best possible protection, the shield must cover the wires all 360 °around and in addition ensure a firm and vibration-proof connection between the cable‘s shield and the cable gland.

Metallic Pipes and Cables A good EMC contact effectively shields the wiring and electronics inside an apparatus by receiving the interference and directing it harmlessly to the ground. Parasitic current Data link Contact Metal shield Enclosure

Progress® EMC easy. Connect Installation feedback due to fast, easy and safe installation Compact size with large clamping range Cable can be rotated, moved and dismantled during the installation process No destruction of damage to the braided shield due to contact springs Optimal shield contact No need to cut the shield to size Whole kit of Progress system can be used

Progress® EMC Series 85 The Cable Gland Series 85 is the flagship of Agro EMC Cable glands. Excellent shield contact: A perfect shield contact over a wide surface area is granted with the collets. As a result of this excellent damping characteristics are achieved. Highest leakage currents: The massive collets guarantees a concentric, low –impedance screened tap connection and handles leakage currents of up to 1. 6 k. A continuous – and short term to 3 k. A

Progress® MS EMC The PROGRESS MS EMC is unique because of its simple technology and its optimise shield contact. Low contact resistance: The immense 360° contact surface ensures low contact resistance. Permanent contact pressure: The interlocking “sealing insert/contact sleeve” combination ensures permanent contact pressure of the braided shield against the lower part.

Progress® EMC Rapid Short mounting time: You have two options of mounting: A: you lead the cable shield through the gland, or B: you cut it to length in the cable gland. Flexible termination methods: If lowest impedance values are required, the contact disc can be removed and the trimmed shield can be connected to the contact bushing.

Explosion hazard + Gases gaseous liquids Aerosols / mist Dust + Oxygen = Ignition source Explosion

Directives & Regulations ATEX 95 (atmosphère explosible) regulates the explosion protection in electrical installations in the EU. The operator company has to make a risk analysis based on the Directive 1999/92/EG (ATEX 137). He has to define the ignition protection categories and the zone category.

Zone classification

Zone classification

Ignition categories Flameproof enclosure “d” • Components are housed in an enclosure capable of withstanding the pressure of an internal explosion (cable glands: 30 bar) • Enclosure prevents transmission of the explosion to the explosive atmosphere surrounding the enclosure Increased safety “e” • Increased safety “e” is an ignition protection type for devices which do not have an ignition source during normal operation. Intrinsic safety "i“, • A circuit is intrinsically safe if its amperage and voltage are limited in such a way that no sparks or thermal effects can occur it.
