交流真空断路器ZW30-40.5kV
用途
ZW30-40.5型户外高压交流真空断路器适用于40.5kV、50Hz三相交流系统中的户外高压开关设备，可供工矿企业、发电厂及变电站作保护及控制之用，也可作联络断路器用，并适用于频繁操作的场合。
结构及特点
该真空断路器总体结构为三相分立瓷支柱式，真空灭弧室装在上瓷套中，下瓷套为支柱，保证带电部分对地绝缘，瓷套内有绝缘拉杆，三相装在一个共同的底架上。断路器健外前3只户外电流互感器，每只互感器可以选择四个不同准确级次参数（即相当12个套管式置感器），断路器也能带12个户内套管式电流互感器；互感器可接在出线端，亦可接在进线端，并且任行电流等级下其准确级次都可满足用户要求，而且可以做到一次、二次互不干扰。
订货须知
认真填写所需产品型号、规格、名称及数量以及基本技术参数；确定弹簧操动机构分、合闸线圈的操作电源（额定操作电压/操作电流）；确定使用环境条件和污秽等级（或产品爬电比距）；确定所配电流互感器电流的形式、电流比、准确级次和数量。用户有特殊要求，也请详细注明。
Basic Use
Tapecoat H50 Gray is designed to protect above ground, buried or submerged metal surfaces from corrosion and electrolysis. It is used for coating pipe, pipe joints, fittings, couplings, tanks, pipe type cable, conduit, tie rods, elevator casings and other metal surfaces. Its unique "MAF" film backing has been specially formulated to provide strength that allows it to be pulled tightly around fittings and other irregular shapes with minimal pull back due to memory. Tapecoat H50 Gray is resistant to UV rays, thermal expansion, impact, abrasion and can be applied over a wide range of ambient temperatures.,
Composition
Tapecoat H50 Gray is composed of a Gray specially formulated multipolymer alloy film "MAF" with a synthetic elastomeric adhesive. Blended in the adhesive is an integrated primer. This primer is kept from permanently bonding to its backing (while in the roll) by a tough, easily removed polymer release liner which prevents contamination of the primer and adhesive prior to its use.

Surface Preparation
Surface must be clean and dry. SSPC-SP3 Power Tool Cleaning is recommended to remove any loose rust and scale, dust or dirt. A "Tack Cloth" for removal of fine dust particles is provided in each carton. Oil, grease and all other residue are to be removed from pipe surface per SSPC-SP1 Solvent Cleaning. SSPC-SP 6 Commercial Blast Cleaning is also acceptable.
Primer Application
Because H50 Gray comes with an "integrated primer" built into the tape, normal liquid primers are not required. However, if the application is taking place in periods of extreme cold (below 40°F) a liquid primer will enhance the immediate bond. TC Omniprime is the compatible primer for use with Tapecoat H50 Gray. Apply primer to the prepared surface by brush at the rate of approximately 300 square feet per gallon. Let primer dry before applying Tapecoat H50 Gray.
Tape Application
Spiral Wrap: Tapecoat H50 Gray is applied by removing the release liner and spirally wrapping in a single thickness with a continuous overlap of tape. Tension in wrapping should be enough to obtain conformability to the surface being coated.
Cigarette Wrap: Precut strips of Tapecoat H50 Gray to a length equal to the circumference of the pipe plus a minimum of 4". Follow general tape application instructions described above.
NOTE: Tapecoat 2025 (Terra Shield) Rockshield is recommended in areas where soil stress is expected.
